This trial game was tested with revision a583d24. There are a couple of steps that need to be taken before it will work on JPCSP as this trial game has a KIRK key (0x60) that can't be decrypted by the emulator.
Procedure:
1) Extract the contents of the EBOOT.PBP with software such as PBP Unpacker 0.94
2) Use a real PSP to decrypt/decompress the DATA.PSP file with the homebrew application PRXdecrypter 2.7a
3) Assemble the EBOOT.PBP back together by using the new decrypted/decompressed DATA.PSP with PBP Unpacker 0.94
There doesn't seem to be any visual or audio issues while playing the trial game, but I did find it unusual that this appeared on the logger:
