Re-flowed my cartridge slot pins, now game saving is disabled, and my sd2snes won't access the sd slot.

Before I try and flow everything all over again, I was hoping someone knowledgeable might be able to determine which pin might be causing my issue. It worked before I did the re-soldering, and I was hoping to remedy an issue with bad cartridge connections, but now I've created another issue. Again, I am unable to access the SD on my sd2snes but without an sd it loads "no sd inserted!" and if I push one in then, it sticks on "loading...". When I inserted a FFVI cart the game doesn't access any save data and will not allow saving from save points. I also tested a super game boy which had some graphical issues in the actual games. Otherwise seemed fine.

I did find this pinout information. Thanks.

Hey man. I dunno if this is still a thing or if you binned it and moved on but I could give you a hand if you like. First thing I'm gonna ask for is in-focus, clean pictures of all areas you've done work. Carefully clean the flux if you haven't, so we can see exactly what we're dealing with.

PS: My former-life job, for nearly 30 years, was servicing consumer electronics. Everything from those programmable LED roadside text signs to modern smart phones, game consoles, DIY whatever - I mostly tell you this to give you the hope that we might actually solve this, if you're willing to put forth the effort on it. Let me know if you want my input, otherwise have a good one!

I think that was a spambot, with some random copy/paste.
At least I couldn't imagine human beings to wire NES connectors into SNES consoles.
But if it was legit, then I would want to see a photo of that, too.

Not only won't they fit as they're 2.5mm pitch instead of 2.54mm but their pin amount is different, too.

Too many one time posters / SPAM bots registering here lately...
