I am playing Pokemon Sapphire and when I save in game and close the emulator, I come back and cannot load it, can only start a new game. I am really new to using ROMS and emulators so I apologize, how can I save my game? Thanks in advance.
Go to the "NO$GBA Setup" (Emulation Setup) which should be under "OPTIONS" (think shortcut is keyboard button Ctrl+F11). Click drop down box "NDS-Cartridge BackUp Media", change it from Auto to Flash 512. That's the save file size for most if not all Pokemon NDS game series. Prese "Save Now" or "Ok" to save changes. Then load game rom, try save in-game again to find out if solved.
