I, feeling a sudden need for a SNES again, went down to a local game shop & bought a busted SNES for $10.
W/O even checking it out, I pull it open & jump the fuse. It's a 1st revision w/ the SPU daughter board. I plug it in, only one game out of 3 plays (Logic Bomb, other 2 where Super Metroid & Starfox). My first instinct was to reseat & flip the connector, didn't do anything.
Anyone know what's wrong? I'm scared...
Bump. My scaredness level has reached a level of scariness that no one has ever been scared of before...
Try more games, especially early simpler ones like Super Mario World. Not enogh data so far.
Sadly these are the only games at my disposal. What the hell happened to my collection of 20-30ish SNES carts from my childhood...
Reseat the internal connector, put cleaning solution on a cart's "golden fingers", insert, eject, insert eject, insert and it should play.
Lol, that's like the FIRST thing I did!
EDIT: I just had a thought, maybe this has to do w/ the amount of amps going into the mobo! I've never had an official SNES AC Adapter for like 6 years, so I've been using any 7+V AC adapter I could find & cut the tip off of it. The one I'm currently using works just fine w/ a rev 2/3 system, but since this one has the SPU daughterboard maybe Super Metroid & Starfox are taking a few hundred milliamp too much...I'll find a higher AC adapter to use tomorrow & see if I'm correct...
Holy shit, you're feeding your SNES AC? I think they do have a reverse-polarity diode, but that's not a good rectifier. Also, the NES power adaptor is 10V DC. 7V AC will rectify to significantly less, especially with a half-wave one made of a single diode.
I said AC? Meant feeding it DC, lol.
Wouldn't it be an AC adapter since you are adapting AC? Was the NES 10VAC? I thought it was 9VAC. The SNES I know is 10VDC.
Run the snes tester rom (from the "burn in/test cartridge") on the snes (borrow a copier from someone). That should tell you fairly accurately whats wrong with it. I have one here which has a duff s-cpu, the divide registers don't work properly and hence just about nothing runs except the copier menu, the tester rom, and mario paint.

lol, this thread! I still don't have a SNES controller to use on this unit (I bet one'll show up somewhere in my attic or something), once I do I'll test my original theory that the mobo isn't getting enough juice, THEN I'll investigate further if necessary.

I've got a 1/1/1 here that flips the tiles around on all sprites larger than 8x8. So yeah, you can play any game that doesn't use sprites.
I disabled the CIC and plan to use it with my dead-SRAM copier (it isn't the socket IC SRAM chip, I've tried replacing that) for stop-n-swop tasks.

Or SMB1 in All-Stars. Doesn't that one use 8x8s almost exclusively?
