I am going nuts over an MK sound board that won't speak! MK y-unit board, seems to work despite being picky about voltage.
In test mode I only get 1 Bong in sound test, but in the sound play test I only get the background midi tracks. In game the midi plays then dies/goes into echo mode after maybe 1 minute.
I have checked or replaced all the caps, re-burned the eproms, replaced the YM3013 and the OKI chip (getting good at smd chips!), and the 8mhz crystal (getting pulses from the other according to my probe).
Ideas?
