Usage

Hardware

To use this minimig core on the MiST board, you will at the minimum need an SD/SDHC card, formatted with the FAT32 filesystem, an USB keyboard and a compatible monitor / TV. Joysticks & mouse can be emulated on the keyboard. You will probably want to attach a set of speakers or headphones, a real Amiga or USB mouse and a real Amiga joystick or an USB gamepad. The MiST board is needed, too, of course 😉

Software

The zip file above contains a minimig-mist-xxx.rbf file, which is the FPGA core, and a firmware.upg file, which can be used to upgrade the firmware on the ARM microcontroller (usually, there is no need to upgrade the firmware, unless it is specifically mentioned to do so). Both files should be placed on the root of your SD card. If you want this core to be the default, you need to rename it to core.rbf.

To use the core, you will also need a Kickstart ROM image file, which you can obtain by copying Kickstart ROM IC from your actual Amiga, or by buying an Amiga Forever software pack. The Kickstart image should be placed on the root of the SD card with the name kick.rom.

The minimig can read any ADF floppy images you place on the SD card. I recommend at least Workbench 1.3 or 3.1 (AmigaOS), some of the Amigas great games (I recommend Ruff’n’Tumble) or some of the amazing demos from the vast Amiga demoscene (like State of the Art from Spaceballs).

The minimig can also use HDF harddisk images, which can be created with WinUAE.

Recommended minimig config

  • for ECS : CPU = 68000, Turbo=NONE, Chipset=ECS, chipRAM=0.5MB, slowRAM=0.5MB, Kickstart 1.3
  • for AGA : CPU = 68020, Turbo=NONE, Chipset=AGA, chipRAM=2MB, slowRAM=0MB, fastRAM=24MB, Kickstart 3.1

Controlling minimig

Keyboard special keys:

  • F12 – OSD menu
  • F11 – start monitor (if HRTmon is enabled, HELP key otherwise)
  • ScrollLock – toggle keyoard only / mouse / joystick 1 / joystick 2 emulation on the keyboard (direction keys + LCTRL)

Features supported

  • chipset variants : OCS, ECS, AGA
  • chipRAM : 0.5MB – 2.0MB
  • slowRAM : 0.0MB – 1.5MB
  • fastRAM : 0.0MB – 24MB
  • CPU core : 68000, 68010, 68020
  • kickstart : 1.2 – 3.1 (256kB and 512kB kickstart ROMs currently supported)
  • HRTmon with custom registers mirror
  • floppy disks : 1-4 floppies (supports ADF floppy image format), with normal & turbo speeds
  • hard disks : 1-2 hard disk images (supports whole disk images, partition images, using whole SD card and using SD card partition)
  • video standard : PAL / NTSC + preliminary support for programmable display modes (640x480x60Hz)
  • supports normal & scandoubled video output (15kHz / 30kHz) – can be used with a monitor or a TV with a SCART cable
  • peripherals : real Amiga mice, real Amiga joysticks, USB keyboards, USB mice, USB gamepads, MIDI in / out
  • could potentially support anything that can be connected to USB (ethernet, RTC, USB Flash, …)

Building minimig-mist from sources

  • checkout the source using this link
  • download / install / build an ARM GCC toolchain (install script here, or alternatively, download an already build arm-none-eabi-gcc package for you operating system – requires support for ARM7TDMI)
  • download / install Altera Quartus II (latest supported version for Cyclone III FPGA device used on the MiST board is 13.1; I’m still using version 10.1SP1)
  • if you are using linux and have the $PATH variable properly set up, you can use the Makefile in the root of the project, otherwise build the ARM firmware using your favourite tool / GUI (firmware is in fw/mist), and build the core using Quartus GUI (project file in fpga/mist)
  • place the firmware.upg & minimig-mist.rbf files on the root of your SD card (optionally, rename minimig-mist.rbf to core.rbf to make it the default core)
  • don’t forget to place kickstart ROM of your choosing on the root of the SD card (these are still copyrighted, so either copy the ROM from your real Amiga, or buy AmigaForever)
  • place some ADF (floppy disk images) of your favourite games / demos / programs on your SD card
  • optionally place minimig.bal, minimig.art & minimig.cop files on the root of your SD card for a nice bootup animation
  • enjoy minimig! 🙂

      Hi!

      The prerequisites are of course a MiST board and an SD card, either of SD or SDHC type. The SD card should be formatted with FAT32 filesystem.

      1. You will need to place the minimig FPGA core file (minimig-mist-XXX.rbf) on the root directory of the SD card. You can optionally rename this file to core.rbf to make it the default core.
      2. You will need to place an Amiga kickstart ROM file on the root directory of the SD card. This file must be named kick.rom (once you have minimig running, you can save a config with a differently named kickstart ROM file). Suggested ROM is either version 1.3 or 3.1.

      It seems I messed up the support for the Cloanto (AmigaForever) kickstart ROMs, so these ROMs are currently *not* supported. I will fix it ASAP.

      Those are the basics. Besides that, you might need to upgrade the ARM firmware (download the latest firmware.upg version from https://code.google.com/p/mist-board/source/browse/#svn%2Ftrunk%2Fbin%2Ffirmware, or use the one included in the minimig release zip file).

      If you want to change video output options (SCART / VGA), you will need to create a mist.ini file on the root of the SD card (see here: https://code.google.com/p/mist-board/wiki/DocIni). By default, the core will output a VGA signal, appropriate for a modern computer monitor (but unfortunately, not all monitors will work due to the specifics of the Amiga video signal).

      There are some additional files for minimig boot-up screen in the release zip file (minimig.art, minimig.cop, and minimig.bal).

      You can place ADF floppy images of games, demos, Workbench on the SD card in any directory.

      To recap: you only need the minimig FPGA core file (minimigXXXX.rbf) and the kick.rom kickstart image.

      Also, please explain what kind of problems are you having in more detail. Is the minimig the only core that doesn’t work? Do you see anything on your monitor? Do you see the minimig boot screen?

      Oh, and your SD card shouldn’t be a problem – I’m using a 16GB one. But there are some rare SD cards that seem to behave strangely adn don’t work on the MiST board or any other minimig board in general. I only know this from people reporting it, I never came across one myself, and I have tested at least 15 SD cards.

      Cheers!

  5. First of all, thanks for creating this core! It already brought me a lot of fun to work with. Awesome job!!

    I have a little problem where the screen is cut off at the right side, as seen in this picture:

    http://postimg.org/image/saotqt9dx/ (pic is taken upside down, sry)..

    I also see this during the loading screen of the core (when reset button is pressed) during the boing ball intro screen. The text to the right is slightly cut off. Can you tell me how this can be prevented? The other (non-aga) cores are not having this issue.

      Hi,

      yes, I’m aware of this problem. The AGA bitplane scroller is not implemented completely correct, so sometimes one pixel on the right or on the left is hidden. I’m still looking into how to fix this – it’s just a pixel output delay problem, but currently I don’t see what the correct delay should be in each case.

      I’ll let you know once I figure this out.

    Hi there! I encountered Problems when starting iGame (based on MUI, requires 020). When starting in WinUAE/fs-uae with similar Config, everything’s working fine, but on MiST with AGA-Core 1.1, I get a Guru.
    Kris said, that maybe some used 020-OPs aren’t implemented in the Core right now. How can I troubleshoot this?

      Hi,

      it’s been a while since I used iGame, but I’m sure it used to work, at least some time before AGA updates. I’ll try it out and let you know what I find.

    • I just wanted to say that I’m very happy with this update! This really comes close to the real deal, and I must say I also prefer stability over speed. This core is a major improvement for many games. Thank you!

    Hi there!

    me again 😉
    I’ve got some questions regarding hdf-Integration. As long, as only FAT16/FAT32 is supported, larger Filesystems than 4GB can only be implemented by using whole Partitions on the SD-Card itself.
    I’ve done that with a 8GB SD-Card, having a 100MB-Fat32-Partition for Core and Kickrom, and having the rest of the SD-Card used as MMC Card Partition 2 as Master in the OSD. This Partition on the SD Card is parted in two Partitions with PFS3.

    So far, so good.

    I tried to port that scenario to an 16GB SD-Card using a patched Kickrom with scsi.device 43.47, but having trouble to with parting that in OS3.1 with HDToolbox. Reading out the Drive Specifications always returns crap.
    I already tried to set the params manually but still no effort.

    I then tried to use two Partitions on the SD, each smaller than 8GiB. I noticed, that it seems to be impossible to configure Master and Slave in parallel. Each time I configure a Slave and reset the MiniMig-Core, the Slave is “disabled” afterwards.
    Is there a guide available with the actual Limitations?

    Regards,
    Uwe

    Reply
    • uwi_u says:

      It seems like the physical Limitation for hdf’s written as Partition on the MiST-SD seem to be 8GiB. I tried a 14GB-Partition yesterday and only got a red screen. Next try will be to place 100MiB FAT32 as primary Partition for core, config and kick on an 16GB-SD and placing a second Partition with 8GiB (i will configure 8191MB) to repartition within the MiST. If that works, I’ll try to take the rest of the SD-Card for an additional hdf:

      Partition 1: FAT32, 100MiB: Core, kick.rom, mist.ini
      Partition 2: non-formatted, 8192MB: Master in MiniMig AGA Core
      Partition 2: non-formatted, ~7000MB: Slave in MiniMig AGA Core

      Stay tuned!

        Hi,

        using more than 8GB partitions was never tested, at least by me. I’m not even sure if the problem is on the software side (AmigaOS scsi.device & filesystem) or on the hardware side. I’ll look into this & see if it can be fixed.

        Reply
          • uwi_u says:

            My recent setup now includes 100MB FAT32 for Core & Co and two Partitions slightly smaller than 8GiB, which I then mounted in the MiniMig-Core as MMC-Partitions and parted into two ~3,8GiB PFS3aio, now having 4*3,8GiB Partitions (working!).

  8. Juri says:

    hello uwi_u

    how can you access the two 8gb partitions with Winuae? (for file transfers) and is it possible to format both partition with only one 8gb pfs3?

        The only “bug” i have discovered is when i load my saved settings it always starts without my 24mb fast ram. Even if it says so in the on screen menu.

          There are still some 020 instructions that are not implemented correctly in the CPU core – the bitfield instructions especially have problems, so you can’t use fblit for example.

          I have already fixed the fastRAM ‘disappearing’ problem – the fix will be included in the 1.2 release.

    Hello Chaos,
    Happy to hear you’re working to next update, good luck on sorting out bugs 😀
    Is the “help key” mapped in next update? i think there are some other key missing,
    i noticed the firs tow of key (not the function keys, but where the normal numbers are) contain 15 keys in amiga keyboard, but 14 keys in PC keyboard.
    One idea would be to include a txt file containing all amiga key codes and all pc key codes, so people can create their own remappings 🙂
    keep the good work and happy 2016

      I haven’t fixed the HELP key map, but I’m sure I’ll fix it for the 1.2 release.
      User keyboard mapping sounds good, but this won’t be in the next release, I’ll think about it later. It’s not hard to do, but it would eat a large chunk of ARM controller’s RAM.

        Will 1.2 have an 020 “AGA” fixes?

          Thanks for offering to help with testing! Right now, there’s not much point in testing, as the builds are pretty rough. But once I get closer to a stable build with most if not all the features, I’d love it if you could test it a bit.

          Yes, I heard, but the FPGA Arcade guys have yet to publish any code to the public.

          The RTG hardware is not too problematic, I can probably write something working in a day or two, as long as there’s enough memory bandwidth. The RTG software driver might be a problem, though.

            Maybe.

            There seem to be some new developments in the Picasso96 software / DDK – apparently the Apollo team is negotiating buying the software from its authors.

            I guess we’ll see if this is a good or a bad thing.

  16. Juri says:

    V1.1 is a nice good state, lot of games work, some dont but if you try some “workbench” usage you’ll end up in breaking the core..
    try to move lot of files from a partition to another with Directory Opus.. if you’re l’lucky you’ll end up with a guru meditation and unvalidated partition… but if you’re NOT lucky you’ll end up with various colour screen (most times yellow , red and black), you have to reset minimig and you lose the partition you was writing on (you have to recreate and format the partition!!)
    RTG would be really a nice addon, but i would concentrate to have a bugfree 020 simulation first.. what’s the use of an RTG graphic if the amiga is unusable?

    Reply
    • Rainer says:

      I merely asked if RTG was doable since to me this is important. Otherwise I don’t think I have much use for the MIST since I don’t just want to play games on it. I even reported a GM I get with ClassicWB.

    hello Chaos,
    i’m a little bit confused, ever thinked the official minimig-aga core for mist was this, and ever followed this page (i own mist device from sept, 2015)
    however i randomly check this other page to verify if there are some other cores updates: https://github.com/mist-devel/mist-binaries/tree/master/cores
    yesterday i checked again and with my surprise i found a minimig-aga core update!!!
    “History
    core_160129.rbf
    68020 bitfield fixes and barrel shifter”
    but in your page ( https://github.com/rkrajnc/minimig-mist ) there aren’t any updates..
    so what’s going on? actually.. what’s the official minimig-aga core page?
    however, thank you for your incredible work 🙂

      Minimig is an opensource project, anyone can make changes to it and publish the core (as long as the source changes are published also).

      There is no Minimig Inc., or minimig-team to publish official releases, every developer can publish his changes wherever and whenever he wants.

      Till fixed the bitfield instructions in the CPU, and decided to publish the updated core. It’s not like he has to ask me for permission 😉

      I’ll publish my updates here, once I’m more or less satisfied with the stability and features of stuff I’m working on. I don’t see much point pushing out updated cores if I know they will most certainly not work, or will crash often.

      The minimig.net forum is very low-traffic, I guess it’s understandable the admins are not very responsive. Just wait a little longer, and try to ping user boing4000 if you won’t get a response. Did you write anything in the ‘NEW MEMBER – acknowledgement’ topic?

    1.1 also seems to have an odd memory timing issue. Sometimes it boots up with only chipmem enabled. That’s not really a big problem though.

    I haven’t written anywhere, how are we supposed to find that thread? o_O I have sent emails to the admin supplied in the registration mail without success. The first time I went to sign up there that didn’t even work because of forum errors. But it’s no big deal, I really only wanted to ask about RTG support and you also answer here so this is probably the best place for minimig MIST questions anyway. 😀

    Question: do you have any place where you would like me/us to report bugs?

    I am getting some graphic bugs in a Demo celler Love from Fairlight. Maybe you could take a look?

    Otherwise the release works really well.

    Just saw the newest core V1.2. I have one question, because i own an Minimig-V1, but no MIST.

    It`s clear that MIST has AGA, which Minimig not has, but which of the two has a better compatibility to OCS/ECS Amiga software?

    The Minimig is longer on the market and when i look at the Minimig.net, then it`s firmware and core gets alot of updates and fixes over the years. How was this solved in the MIST, when it was new on the market?

    I mean, was the Minimig core with all his fixes/updates that he already had at that time, transformed to the MIST? Or was a comletely new core written for it?

    I ask, because i simply wanted to know, if the OCS/ECS compatibility of the MIST, now is at the same level like the normal Minimig.

    And i have another question to the MIST. How good, from your experiences, are the other cores (Atari-ST / C-64), which are available for the MIST? How high is their software compatibility, are they at the same level like the Amiga-core or not?

    Regards

      Hi,

      both the original minimig and the MiST have the same OCS/ECS codebase, so they should have similar compatibility. It is possible some bugs were introduced by upgrading the core with AGA capabilities, those will be fixed in time (some already have been!). The original minimig also has a real 68000 CPU on it, which the MiST board doesn’t, so the MiST core could have some incompatibilities because of that.

      Minimig for the MiST board is based on my previous minimig core for the DE1 board, which in turn is based on the original minimig core. So no, it’s not a completely new core.

      The MiST has some nice cores for other computers, but I can’t really say how good they are – to me, they seem pretty good, but I only ever had a C64 and an Amiga, and I’m only interested in those two. I did try the ST and the PCEngine cores, they seem to work just fine. My time with the MiST board is mostly spent debugging the minimig core, so I don’t have time to actually ‘use’ it 😉

      With the current CPU core, around 14 MIPS should be possible. With a theoretical new CPU core, around 10x current performance.

    Hi,

    I am an happy user of your core so thank you for your so amazing work.

    I made a couple of tests especially on audio.
    I notice that audio is not really separate as original amiga is.

    Could you tell me more about that?

    Reply
    • chaos says:

      Hi,

      The original Amiga did indeed have completely separate audio channels, but in my opinion that was somewhat annoying to listen to, especially with headphones.

      The MiST board (and minimig before it) has a physical 1k resistor connecting left and right audio channels, thereby mixing the two together somewhat. Unfortunately, this can’t be fixed from within the FPGA core, the only option is to remove the 1k resistor from the board.

      If it’s any help, here’s the schematics of the MiST board:

      https://github.com/mist-devel/mist-board/wiki/Board13

      (the resistor is R21, 1k).

    Hello Chaos,
    do you know if could be possible to add a faster boot mode option to the mist.ini?
    The displayed text when first starting the Mist is very disturbed in 15khz mode, could be possible to get rid of it? Simply turn on Mist, black screen, core load, amiga start… quick n’ simple, without display any text on screen (maybe bypassing pauses if any)

      Hi,

      theoretically, it could be done. But theoretically, the selected 15kHz/30kHz mode in mist.ini *should* already work even for the boot screen, but for some strange reason it does not. I’ll look into it, and when I have a fix for it, I’ll try to implement the fast boot option too.

          There is little to no cooperation with the FPGAArcade guys, unfortunately. If they would at least agree to share their sources, we could easily cross-check and fix any bugs that were present in one or the other version of the code (I guess they still can look at my code, just not the other way around …)

          The minimig project is in dire need of more developers, especially some good software guy(s) would help tremendously.

          And the users – if you really want to help, start testing and reporting any game and demo you can get your hands on, try different settings, compare to real hardware and/or WinUAE, make screenshots of buggy parts, nag any software guys or demo authors that might help narrow down the problem, or anything else you might think of to help me fix the bugs that are present. You can’t expect me to waste countless hours tracking down bugs, thinking about possible solutions, implementing them, compiling, testing, and doing this in endless circles, while all I get from you is ‘Many demos with bugs’.

          Anyway, I started testing some bugfixes, and I’ll provide beta versions on this page (more info will be available in a new post shortly), and I’ll provide some sort of a Google spreadsheet were working/non-working games and demos can be reported.

    I cannot use my MiST with my TV because VGA signals coming from MiST have too low frequencies.

    Is there a workaround for that without using VGA SCART cable?

    Reply
    • Mahen says:

      Many years ago, in the Minimig era, there was once a hack called “60 Hz PAL” which consisted in running everything 20% faster and fixed the need for a 50 Hz display (which is one of the issues you may encounter). It was not a great solution though 🙂

      Another solution would be to display at 60 Hz with tearing. Dunno if that could be achieved. Wouldn’t be that satisfying either 🙂

      Meanwhile you should definitely get the SCART cable !

      Reply
        • chaos says:

          If you a have a PAL TV (probably yes, since it has SCART), the TV *should* be able to show 15kHz output from minimig, so buying a minimig-to-SCART cable will help.

          Otherwise, follow mahen’s advice. Running in NTSC 60Hz mode should work just fine.

          If you want to see PAL 50Hz output on an incompatible (60Hz only or VGA only) TV, sorry, bad luck. Minimig will not in any of its current forms support re-timing from 50Hz to 60Hz or vice versa by itself (since this requires saving a few frames of video), an external device is required for this.

    I have a Minimig original board and no MiST and i always thought the compatibility of both machines is on a similar level.

    But now i read here alot about graphic-problems in some games/demos and that “Pinball Illusions” should not work correctly.

    Is this really true on the MiST, because on my real Minimig “Pinball Illusions” runs perfect and it`s also very hard to find some graphic-bugs. Also on “minimig.net” only a handful of programes (demos/games) are listed, which still have any kind of problems, the rest runs perfect in the meantime.

    So it seems, that the compatibility of the original Minimig-board is better than on the MiSt. Is this true?

    Reply
  60. chaos says:

    The compatibility of the two minimig variants is more or less on the same level, but there are some important differences:
    – the original minimig has a real Motorola 68000 CPU on it, so you could say it has 100% compatibility, while other minimig variants use the TG68 softcore, which, of course, is not perfect.
    – the original minimig only supports OCS/ECS chipsets, unlike minimig-mist, which also supports AGA. Obviously, the larger pool of AGA-only demos and games will necessarily bring more non-working software.

    Pinball Illusions ECS works fine on both original minimig and minimig-mist, AFAIK. The problematic one is the AGA version (which doesn’t work on either ;))

    So, all in all, for ECS software, the two minimig variants are more or less the same compatibility-wise, except for some rare cases where the CPU on minimig-mist is either incompatible or doesn’t have the proper timings.
    Plus, the possibility I introduced some bugs while upgrading minimig with AGA chipset support 😉

      Hehe, actually Pinball Illusions ECS doesn’t exist 🙂

    Oohh, its true what MAHEN said. “Pinball Illusions” is a AGA-only game.

    I confound “Pinball Illusions” with “Pinball Fantasies”, which worked perfect on normal Minimig Board. “Pinball Illusions” can not be loaded on normal Minimig because the hardware don`t support AGA. Sorry for the confusion. 🙂

    Nevertheless, its very very hard to find a game which has some kind of graphic-problem on real Minimig. But here some MIST-users speak about those things. This must be a MIST-only problem. Thanks CHAOS for clarifying the differences between MIST and real Minimig. Now its clear to me, why normal Minimig is more compatible, at least currently.

But, like I said, this is just a fairly straight-forward side project, something simple before I get on with the CPU work (which is a major PITA 😉 ).

I’m doing it ‘properly’ this time – with a bit-accurate C model, which can be tested on PC, and then writing an analogous Verilog model. C model is done, testing done, currently finishing the Verilog code, there are just some corner-cases with the math not exactly matching the C model. Should be done soon.

      The 68080 CPU is closed source, so it is not possible to port it to the MiST.

    I don’t think anybody is making big money with retro commodore hardware. But if you google for “tekmos 68020” you will find a company, that started to sell new 68020 compatible cpus recently, and I don’t think these cpus are meant for new Amigas. There must be a small market for 68k cpus outside the retro community (industry? military?), and I think this is the reason for not open sourcing the 68080 cpu.

    And I think nobody should be blamed for not open sourcing. The Apollo team must have spent years in developing the fastest 68k cpu on earth. The rest of us can live with the TG68 for now, it’s fast enough to play Doom on the MiST 🙂

    Maybe the same thing will happen, that happened to the Minimig V1 board back in time? When Acube stopped selling them, other companies came and sell the parts or the complete board. And if not, then similar boards will come. There are more and more FPGA products on the market.

    True, but I don’t agree that MiST is a history. Amiga has never died, Minimig is still alive and MiST will also never die. It has been bought by so many users so that it will never go down. The SW development will continue I suppose – of course within its closed architecture, so I don’t know how much is still to reach since many high-quality cores are already available. Besides I am having fun with my MiST with Amiga core further on no matter if it stops getting produced or not. It is open-source so any time you can have it build “on demand” by many electronics firms anywhere or do it yourself (of course as long as parts are available…). Besides it is clear they couldn’t produce it till doomsday. Maybe Till will propose a good successor? I love this device! So let’s hope for the best! 🙂

      Many thanks for people who made this release possible. Nice to take benefits from Mister works to keep our Mist alive…

    Hello! I picked up the MiST @ amigastore.eu and really like it so far. Thank you for this amazing machine! Only AMiGA makes it possible!

    I have noticed a few odd things I’d like to share in case it can improve the code, I have used version 1.2 exclusively:

    1. First boot I saw a GURU screen that somehow magically fixed itself and I’ve never seen it since
    2. Installing OS 3.1: All went fine up to rebooting after making partitions, when booting from the “Install” floppy I’d get checksum errors, I could successfully install after pressing “Cancel” a few times though, this error also magically fixed itself after I re-copied the ADFs to the SD card’s first partition
    3. Some times the left mouse button would get “stuck” / not registering a click, this could be fixed by pressing the left button on the USB keyboard mousepad though
    4. HDFs created in WinUAE (mounted as “Disk file” on the MiST) where “Surfaces” > 1 : Are they supported? I got “not a DOS disk” trying to boot (it seems number of surfaces must be set higher in WinUAE to have HDFs larger than 1GB)
    5. Regarding mist.ini’s “scandoubler_disable”, is it true that if something is connected to the 3.5mm audio jack the MiST will disregard this setting? (I’d get picture with VGA but not SCART until I pulled out the plug)
    6. Slam Tilt Pinball (AGA) HDD version will boot but is stuck after selecting the table

    Again, thanks for this amazing machine, I look forward to trying out more software on it 🙂

      Hi,

      since MiST currently only supports FAT32 filesystem, creating files bigger than 4GB is not possible. But you can always use a bigger separate partition for the Minimig core.
