I'm looking mainly for a DS flash cart that also works for the 3DS I would mainly like to use it for backing up my GBA pokemon ROMS from my retail cartridges to the flash cart and then from my flash cart to my PC. I would also like to back up the save file from the retail cartridge to the flash cart and then from my flash cart to my PC. I would then like to play the GBA pokemon game and save on pc with an emulator, and then save my game on my PC. I then would like to transfer the save back from my pc to the flash cart, back to my retail cartridge. The benefit of it workign with 3DS would also be great because I have a 3DS, for other projects. Any recommendations on a flash cart that would allow me to do this? I have a 3DS XL, and the original gray fat DS that came out first when DS came out. Thanks for any suggestions. I also already have micro SD cards. If you can recommend a flash card for me and a website that you would recommend that would be great. Thanks. I'd keep my backuped ROM for my use only, and for my personal use only.
