I'm having an unusual problem: My EZ V (running the latest menu) can see the SRAM on my 3in1 (second rev, New3in1) but nothing else can. ExpLoader always asks to initialize it and dumps it as all 0s for all 512KB when I select the option to dump the entire SRAM, SRAM test fails on writing the first byte, etc. The weird thing is that I have a GBA game save on there and it works fine, plus I can save/load normally in the game that's flashed to NOR, even after days of having the DS switched off. When GBA ExpLoader puts a game in PSRAM and boots to GBA mode, it runs the game in NOR, but doing the same thing from the EZ V menu works fine; the game loaded to PSRAM plays and saves as expected. I can start GBAldr; it produces a 512KB all-zero file and doesn't touch the GBA save in SRAM even though it's supposed to wipe SRAM. I can't imagine how it'd be the battery, since it retains GBA save data while unpowered yet can't be successfully read or written by homebrew. Any idea what it could be? I'd be happy to run any tests or diagnostics that anyone suggests. Thanks.
