Hi everyone,
I have a strange problem with an MVS MV-1FZ I recently purchased. I read extensively here looking for a solution to my problem but I can't figure it out.
I cleaned and did the 5v only mod to the board. I have already done this to another MV-1FZ that's working fine, so I'm certain that I've done this right.
I am also using a Unibios 3.3 that I've burned myself, which is also working.
To the issue now, the MVS boots up just fine without a cartridge to the crosshatch. I have no trouble with anything, calendar works, did a memory test for 10 minutes.
I also tried the DiagROM. All tests pass, individual tests pass, too. Memory test passes there as well for 10 minutes.
As soon as I put in a cartridge, either an original, or a 161 in 1, I get the watchdog with a quick reset and clicking. (Cartridges also working on the other MVS).
Anything I can try, or focus on?
Thanks!
