I got this to work exactly once past the rebooting when switching a gba cart, but i realized my ftp server wasn't on and i ended up restarting. Now I can't get anything to work because it says it can't backup a gba game.
I dont WANT it to back up a gba game i want it to fucking work with black 2.
edit: got it to work at least to the writing phase by:
1. put in gba and acekard2i (with snapshot 1)
2. launch flashcart
3. pull gba game
4. launch sgm
5. press b then backup save menu
6. put in gba game, pull flashcart
7, put in new game, doesn't restart. NOW pull gba game after new game is in. It wont restart.
However in these steps i'd get to 71% and then it says "error, wrote 512 got 47"
edit2: It said it backed it up, smallftp says uploading then just times out and i dont actually have the save file.
