I'm a little-bit in the same boat you're in, Mongo51983... I've been looking for an emulator for Battle Arena Toshinden, but no such luck. They [3D Fighters] aren't even covered in MAME.
They are, Virtua Fighter 3 can run in MAME, have a look round and u'll be able to play it, Battle Arena Toshinden 2 is on MAME and playable by the way Shpongled.
Use ZiNc for Battle Arena Toshinden 2 as well as a whole list of fighting games, Dead or Alive ++, Soul Edge, Street Fighter EX, EX 2, EX Plus, EX 2 Plus.
Thanks for the info, Mongo & Darth. I've tried BAT2 and SFEX in MAME, but the sound is very poor -- echoing effects -- and the graphics are sluggish and very-unlike the arcade versions.
I was thinking it's my computer, but I'll try that ZiNc. Thanks for all the info. Good luck on your Virtua Fighter 3.
