DJ MAX Portable 2

[djmaxppssppplayer]

Another Case Plz Help:

DiscID: ULKS-46116
Version: v0.9.8-329-gb3db6a (64-bit)
OS: Windows 8 (64-bit)
Notes: The game becomes unplayable when playing the third song.

I am sure that this problem is not caused by OS nor my version. It is the ISO itself. The ISO is extracted directly from my UMD through USB. Whenever I play the 3rd song, the game starts to stutter and deformed sound and graphic glitches on videos and gear. It should be the anti piracy protection of DJMAX according to a post in github.com.

However, ISO tool will not patch this ISO as this game is too old, and the only way to play this game was to change the UMD ISO Mode in XMB in order to play it in the past, which is not an option in PPSSPP.

This person can complete all 4 songs without any problem:

Please help. I struggled for two days about this issue.
