Retrode 2 corrupting SNES sram?

[Driftwood]

I just received my retrode 2, and the first thing I tried was to back up my saved games from my US Secret of Mana cart. Unfortunately, the srm file produced by the retrode doesn't work on my sd2snes, in Higan, or in SNES9X, and when I tried my cart in my Super Nt, I can no longer access my existing saves.

I read a similar post of someone having a problem when trying to dump their gameboy saves, and the problem ended up being a manufacturing problem where one of the pins was bent, but I don't see any obvious issue with the pins in my unit (see attachment -- sorry about the low quality but the board has a 128k limit on uploads). I also saw issues with snes saves when the unit was set to 3.3V, but I double-checked that I have it set to 5V, but no luck.

I've attached the srm from the retrode2 if anyone can help me figure out how to rescue my saves, but it would be nice to know why this happened or if there is a fix.

Thanks in advance.
