The romset for these old mame versions I don’t even know where to find and what version to look for. Also, it was sometimes written around here that not all roms work, even though they’re reported to work.
xor tables are some missing files roms need.
For example, D&D: Shadow over Mystara (Euro 960619) doesn’t work on mameadv if you don’t have dd2ex.04e and dd2ex.03e inside its zip. In fba, yes, perhaps (haven’t tried it). These can be found in a dedicated site, cps-2 shock.
For fba, I even found a complete rom set from some guy over the internet that even though they supposedly work, in practice, some of its roms don’t. Pm me if you know more about this subject (roms, sets, etc).
And it’s Good to know that progear works on fba! Thanks for that.
