I attempted to Play the game KOF95 and Ultraman which is working with expansion cartridge.
The game was not working. It was just a message saying that the ROM pack wasn’t properly inserted.
I’ve already placed the bios (mpr-17933.bin, mpr-18811-mx.ic1, mpr-19367-mx.ic1, sega_101.bin) in the folder ‘retroarch/system’
so I tried another way mednafen 0.9.48 + mednaffe GUI. this system is worked fine the KOF95, Ultraman. but Mednafen 0.9.48 + retroarch 1.64 ~ 1.70, WIN10, 64bit version didn’t worked.
If this is a bug, I hope it can be corrected and if there is a way to be normal, I hope you let me know.
