Snesp (almost finished)

oh... well I'm guessing the cart slot relocation is guilty.

Wow...that sucks for you

It may be the fault of the cart slot, for there are, like 60 wires on that and if just one fails, its possible that no games will work. Also, is your console gnd attatched to your screen gnd? That could be a reason.

Not all games use all pins, so try with a bunch of different games. If one or two out of ten work, than its the cart slot.

It could also be a power issue. Maybe you have too high or too low of voltage to the snes. I don't know, for I am unaware of the snes voltages. If this is the case, I pray for you that it is too low, otherwise you blew this project..literally

Good luck...

(p.s. this is why you test after EVERYTHING.)

63, actually. And yeah, it'll be pretty hard to figure out what's the problem, so you'll just have to go test everything. First of all, I'd go use a multimeter to make sure that the snes cartridge port is wired correctly (stick the one end between two pins of the port, and check if it's getting something at the right two pins), next make sure there are no shorts between two pins (again, multimeter)

Don't do that. On ym N64, I rewired it wrong, and DK64 would boot, Mario Kart was fine, but Super Smash brothers did not. Got a new N64, and guess what? I fried it.

I got the superior Japanese version on eBay, though, so I am ok now.

Wow, that looks very nice. Great job, it's beautiful!

Definitely test the SNES before opening it next time.

and more importantly, between the steps

Sorry, Mario, I quoted YOU instead of the above quote, the right one.

Read this a bit wrong.

I will test card slot but i think the connection are good, it is possible that the problem come from negative wire of the snes card, where do i solder the negative wire?
my wiring diagram below, have you seen something wrong?

It looks fine to me. I mean, it looks really really good.

I'm not sure if I remember, but are you using composite for the video connection? The SNES mini doesn't support RGB (or S-Video) directly.

Also, it's super easy to just solder on a composite video cable and test the picture on a TV. That will let you know if the SNES or LCD side is malfunctioning. Good luck!

For the video signal I followed the information given by BEN, one single wire soldered.

Where do you solder the ground of the snes card?

Kyo · Post by **Kyo** » Wed Dec 31, 2008 4:14 am

to the ground of the battery/screen
