I know it's a longshot, but I have a DJ Boy PCB that constantly resets after boot. Here's the closest thing I can find to a schematic:

When I got the board, the rom at 6y failed romident, so I burned a new one -- no change. Reseated all connections. No chips are noticeably warm. It passes the RAM test at bootup, and if I boot into test mode, I can test the inputs, outputs and sound w/o apparent issue.
Any ideas?
Also, what is a 4M MASK ROM? The identifying numbers printed on the chips do not yield much when trying to Google them. How can I read these to make sure they're ok?
