A short follow on video to my original fix to my King of Monsters 2. What is interesting is the fact I think there’s an issue with the PROG16 board and some MVS models, and in particular the sizing of the bypass cap used on A47 when used with certain games.
It’s worth noting there that later (off camera) I swapped out the other 151 (150pF) cap for a 47pF cap as well. I had to do the same thing on the same board (PROG16) on my Fight Fever bootleg. I am speculating that it’s the use of EPROMs on these boards that is generating noise on the board which is affecting the PCM chip, via the SDRMPX and SDPMPX lines. Either that or the size was not spec’d right for the the MV1-FZ.
