Hi,
I got a defective SamSho II cart (MVS) from xsq (thanks again).
The sound is crackling.
Here are some details :
- Intro sound (NEO GEO logo) plays fine
- All the music is distorted either in game or using the jukebox option in the UniBIOS
- All traces from/to the PCM chip, V1/V2/V3/V4 ROMs and the LS139 on the PROG board are fine
- Boards look really nice (no rust, no damaged areas, no scratches, etc.)
Could it be a bad ROM?
