English Progear - CPS2 sound issue

Post by zak »

Hello everyone. I'm currently having a problem with a progear board. The music and sound effects sound very strange past the insert credit screen.

I have swapped the (01) sound rom with another English progear board, but it made no difference, the problem still remains.

I was wondering if anyone else has had a problem like this.

I also wanted to know what would happen if I took all the English roms and put them into a japanese progear?

Any input is appreciated. Thanks in advance.

Zak.

Swapping all the program roms to a Japanese board will not work as the decryption key is unique on every region.

Try swapping all the masked roms, that's where "the sound is".

Hi starke :) thanks for the reply. Are the masked roms the small chips next to the battery?

Also, would swapping the English masked roms with Japanese ones be ok?

Hello again starke :) Which part on the board are you referring to?

The 6 (2 + 4) masked roms to the top right/middle, the big ones.

Try swapping them, I have no idea if it would work but trying won't hurt. All I know is that the program roms have different encryption on different version.
