jurjur What I've checked and I'm going crazy is that with the same bios both in version 5.21 as in 5.22 I have neogeo roms that work perfectly in the x32bit version while in the x64 bit version they don't work ... Can it be that cores / emulators only go in x32 bits? WTF!!!!
joinski jurjur Could you name a few roms that work in 32bit but not in 64bit? Did you check, if the same Emulator/Core is used? (Game Settings, Advanced)
jurjur Yes, the same rom..the same neogeo.zip core..some roms For example...in x32 metalslug 3,4 and 5 run ok, instead in x64 not similar with last kof 2000, 2001,2002 i think that are the new games
joinski jurjur i just tested neo geo on my system (x86_64 PC) and i have a guess: i guess you downloaded the roms from coolroms. because i downloaded from there first and for example metal slug 4 was not working. then i downloaded from another site (wowroms) and the game worked right away.
