GUNDAM VS GUNDAM

[montcer9012]

can some one pls give me a tutorial on how to get the sound effects

It seems someone already did; look here:
at32aa3plugin.jar - mono at3+ decoding

Also, i don't know why you post it here; JPCSP have a dedicated section on the forum; maybe if you post there you will get more help.

By the way, the game you talk about is not listed on the JPCSP list of game tested; you could help to the forum posting there a log info with your results. Also, if an issue is encountered maybe developers will help you to solve it and make this game full playable.

Others games of the serie are listed here: (Look on G part)
JPCSP Games List Part 1

And due your game is not listed on JPCSP commercial games tests, you may want open a thread on the correct section according to actual state of the game with latest rev:
