I've played with it and it's almost perfect from a game preservation perspective except for one glaring feature missing, many old cd games used to read the audio tracks of cds but the ao486_mister doesn't support this. So a lot of games from the exodos collection that would be perfect for this will crash when they attempt to read the audio track.
- anthk 4y agoUse a BIN/CUE format for these games.
- nicolas_t 4y agoEven with bin/cue format, last I tried, it didn't support audio tracks. See this forum thread that talks about it. https://misterfpga.org/viewtopic.php?t=2189 https://misterfpga.org/viewtopic.php?t=2189 It might have changed but I haven't seen anything about that in the change log and the repo still says "Currently only data portion of CD is supported. "
- anthk 4y agoAh, sorry then. At least it parses the CUE files fine. Playing audio CD is shouldn't be a "big" task at all, basically you sent bits from the faked CD drive to the sound card. https://cvsweb.openbsd.org/cgi-bin/cvsweb/~checkout~/src/usr.bin/cdio/cdio.c?rev=1.84&content-type=text/plain https://cvsweb.openbsd.org/cgi-bin/cvsweb/~checkout~/src/usr... Implementing the whole fake unit reading the media would be the most difficult task by far.
- nicolas_t 4y agoI haven't looked into it but what might be complicated is implementing the support for audio cd in the vhdl of the sound card component...
