Armored Core 3 Portable Game Crash

[gamedudeadvance]

Hi, I've recently downloaded this emulator to play AC3 Portable but for some strange reason the game keeps crashing after finishing the "Assault Crest Facility" mission. The game crashes right before the rewards, deductions and credits screen. I've already disabled cheats, redumped, downloaded the ISO from different sites, and even enabled the game fix during a crash option in the cheats, but no luck. If anyone has any additional advice, please let me know. Thanks!
