Just got this board a few days ago! Thank yous go to mahen, who was kind enough to sponsor the board for me (thanks again man, I really appreciate it!). For those not familiar with it, this board is the basis of MiSTer, which is a project that aims to recreate various classic computers, game consoles, and arcade machines on FPGA hardware – and as the name implies, you could say it is a continuation of the MiST…
I know there wasn’t much updates on the minimig status, but with good (;)) reason: I’ve been pretty busy, so I had little time to work on minimig updates. I did spend quite some time on rewriting the CPU <-> minimig interface, which will hopefully reduce timing problems and enable me to finally add the ethernet Zorro interface. The CPU clock will also be reduced to 28MHz, hopefully that won’t affect the CPU speed much. This is quite…
There is a new release of minimig-AGA for the MiST board available, grab it on the minimig-mist page! While the CPU is still not as stable as I’d like, the latest bitfield fixes by Till Harbaum fixed a lot of games and demos that didn’t work properly before. The OSD Turbo option is not needed or recommended for games or demos anymore, but could still be used for a little speed up in Workbench or programs. F11…
Two bugs were discovered and fixed for the original minimig board, and a new release was prepared. The first bug was in the minimig blitter implementation, which was missing an undocumented feature of the original Amiga chipset. When using the blitter in line mode, the first pixel of the line is written to D pointer address, and all subsequent pixels are written to C pointer address. This bug was obvious in demos like SushiBoyz & Sunglasses…
