Terra Onion for the Turbo Randomly Resets

[NEgO MANIAC]

Looking for some help as to why my Terra Onion is resetting during game play. I tried replacing the SD card but still occurs. This the first model and I have on my SuperGrafx. I have never updated the software since purchase years ago so not sure if that is a contributor. Also running a replacement SuperGrafx power supply. Original crapped out a few years back.

What are the specs on the replacement power supply, and do you have another you can try with? Also, double check the connection on the rear expansion port and make sure none of the expansion port pins got pushed back in to the console. I've seen that happen on a TG16 (and it's kind of a pain to fix). Worst case, there's always migration to a TurboEverdrive Pro + EDFX.

This would be my primary guess too.
Since the Super System SD feeds of the GrafX Power supply I would suggest 9V 1.5 A - 2 A power supply.

You didn’t happen to give the power cord a jigglin, did you?
