Hardware Supercard mini sd filesystem screwed up on my gba

[DolphinCube]

hello! I happen to have a supercard mini sd with a micro sd to mini sd adapter. The micro sd card is 2 gigabytes so I think that is fine? Anyway. When I boot up the supercard. the intire filesystem is screwed up! It happens to only do that when its in my game boy. I did try it on a game boy player (thank you game boy interface!) and that seemed to work fine. No lag. I did a system check on it and the only problem is.....

IT COULD NOT FIND A TEST FILE!
If anyone know whats going on here. Please help me out!
My GBA model number is AGB-001
Thanks!

Try to remove the Super Mario Advance game from the sd card.

Do normal game cartridges work in the GBA? It sounds like some pins could be shorting

 

[DolphinCube]

yeah. normal cartridges work. But I do actually think its the Gameboy itself. Because I tested it on a game boy player and that worked fine (for some reason)

Make sure that your SD card is formatted to FAT or FAT16. But if it's working on the GBP and not the GBA, it might be a contact issue. I recommend putting something behind the PCB of the Supercard inside the cartridge to ensure the pins are making contact inside the slot; use tape or a piece of paper.

Ok. So before I do that... 1. Where do I put it behind the PCB? 2. How much tape/paper? 3. If the battery has something to do with this. I think I found the problem.

Just a single piece of tape or paper will do. If it's loose-leaf paper, maybe fold it once as it's too thin. Unscrew the cartridge and place the tape/paper behind the PCB, so it pushes the 32 pins up.


Another problem is the SD card not being read. It helps if you keep reinserting the SD card until it's read properly.

Worst-case scenario: the solder joints need reflowed. https://gbatemp.net/threads/how-to-fix-fake-supercard-mini-sds.340221/
