Por ahy me encontre esta utilidad para regenerar el pro evolution soccer 6:
Modo de USO:
1. Extract the iso with winrar.
2. use this tool (by 0x90) to extract the 0_sound.afs dummy all the files except 1 of about 3.5mb i chose 00000000.afs
3. rebuild it then you can choose to relink it or not depending if you want music when playing the game or not.
4. Then rebuild the iso with UMDGEN but relink the language files and delete the update folder and boot.bin first.
Ojala les funcione.
Saludos
