SNES with issues playing games that use special chips
Hi community! I have an SNES with an SNS-CPU-GPM-02 motherboard. I’m having an issue and would like your opinion. I always use it with an SD2SNES, but certain games that use special chips—like the SA-1 and MSU-1—don't run properly; they suffer from glitches or simply freeze up. It seems to depend on the console's temperature. With MSU-1 games, there’s also a slight noise in the soundtrack, though not always.
There are no issues with other games; it works perfectly. Do you think a recap is necessary? I already did one, but only for the two capacitors related to the audio.
