Anyway here is what I have been working on for the last 24hrs

It lets you copy cartridge savegames from the SD card to the game cartridge and also the other way around.




The only supported flashram games right now are:
- Jet Force Gemini (Flashram Type 1)
- Majoras Mask (Flashram Type 2)
- Pokemon Stadium 1 (Flashram Type 2)

Also confirmed working for me are:
- Super Mario 64 for 4K Eeprom
- Perfect Dark for 16K Eeprom
- F-Zero X and Zelda OOT for SRAM.

I only tested it on the Neo2 SD, I'm not sure if it will also work with the Neo2 Pro.
