"It's not an issue when running from the SD card. You normally leave it set for the default bank (0) and in the Save RAM Manager, turn on the automatic save/restore option, which loads the bank before running the game, then saves the bank to SD the next time the menu is run (so don't forget to reboot into the menu after running the game! ). While in the browser with the game selected, press A for options, move down to the Save Manager option and press C. The automatic setting should be first in the list - press C again to toggle it from off to on. Then press A to exit the screen and then B to run. Once you've set the Save Manager to automatic, it remembers the setting, so you only have to do that the first time you run the game."
I've always hated forgetting which bank I saved my game on. So this should help
