MvC2 Buffer Issues
Posted: Fri Nov 23, 2012 8:29 am
Hey folks,
I'm just getting into Naomi, but have a lot of arcade experience. I recently picked up a MvC2 cart that ran stable for a brief period through a Capcom IO, and then started rebooting and crashing. The self test reports very intermittent results, with sometimes the chips reporting all good, and sometimes others randomly bad. My primary question is that should I be looking at getting those buffers replaced, and has anyone experienced them seemingly working and failing rather than dying outright? Would an official Naomi power supply possibly take care of this issue?
Voltages are (and have always been since the Naomi was installed) perfect and stable, with 3.3, 5.1, and 12.10 on the mainboard, and adjusting them doesn't seem to predictably affect the problem, other than that the system gets more stable when voltages near the recommended ones are being output. Right now I'm running the cart and board uncased to eliminate heat from the equation.
Has anyone else seen the buffer ICs fail like this? I've seen buffers shot on other arcade hardware, and they often are quite dead when they go.
Thanks!
