Well, I gave up, I did run tests, and I am still convinced that my flashcart pcb and NOT the SD card fucked up, how do I know that?
Because I tried 3 different SD cards
All FAT32
With the correct iOS (V2 Everdrive)
Correct Paths
And I am sure that the SD cards weren't the problem, BECAUSE I JUST RUN THE ROMS ON EMULATOR FROM THESE DAMN THINGS, AND NO PROBLEM.
IT IS NOT THE FUCKING SD CARD NOR MY SNES, I clean and run my old carts and they worked fine, even the chip based ones!
MY EVERDRIVE IS DEAD!
