The Simpsons Game - ULUS10295

[gid15]

on the gracie films screen it plays the 20 century song from the screen before which is wrong

Code:

10:03:15  INFO hle.IoFileMgrForUser - user_main - hleIoOpen filename = disc0:/sce_lbn0x236f0_size0x78000 flags = 1 permissions = 0777
10:03:16  INFO       me - user_main - Using external audio 'tmp\ULUS10295\Mpeg-489472\ExtAudio-0.wav'
...
10:03:21  INFO hle.IoFileMgrForUser - user_main - hleIoOpen filename = disc0:/sce_lbn0x237e0_size0x78000 flags = 1 permissions = 0777
10:03:21  INFO       me - user_main - Using external audio 'tmp\ULUS10295\Mpeg-489472\ExtAudio-0.wav'

It looks like the 2 videos have exactly the same file size. Currently, only the file size is used to extract the audio (Mpeg-489472). This explains why the second video thinks the audio is already extracted and is reusing the audio from the 1st video.
I will have to improve this by adding something else to the file name (e.g. the last timestamp of the video).
