Quoted from barakandl:
What sounds are wrong? When the bug is happening the credit noise will be wrong(i think its a beep instead of explosion) and the spinner sound is missing or just a click that silences all other sounds.
After running the RAM clear software did you notice that the audits all got reset back to 00?
I'm having this issue where the sound for my spinner is basically just a rapid click. Guess I've been under a rock about this issue lol. My MPU is one of your earlier versions that had no option to choose the game. I had to pick the game upon ordering and I can't change it now. Will the roms on your site work with my older version? I have a friend who can burn the chip.
