so, i think i've finally sorted out how to use my EZFlash 3-in-1 with YSMenu, for GBA games, and have successfully copied games to NOR, and retained the save information after restart, to backup to a save file. However, i am unsure how to back up the save of games copied to PSRAM. whenever i reboot my DS after playing a game copied to SRAM, using either the A or Y button in YSMenu, the only option with regards to backing up a save file seems to be to back up a save from a NOR. can anyone help me with this problem? Edit: it seems the problem was with a specific game: Tony hawk's underground. maybe i patched it incorrectly. I found out that YSMenu automatically backs up the SRAM from PSRAM games on reboot, so i shouldn't have any problems there.
