I tested in mame 0.197 give erros First time I played this game, was incomplete bor version on the PS2 due to console and ram limitations

I already played the official version in the fightcade emulator I can use it?

Of course you can play it through Fightcade. Some of the coop runs have used Fightcade/FB Neo for the runs.

Some versions (older ones) of MAME for this game cannot work properly, so other emulators like Fightcade definitely is very useful.

I'll download again, thanks

you need download Alien vs. Predator (Euro 940520) for play jap version
