This new version of the emulator contains a Save auxiliary Slot called "Aux" that stores the content of QuickSave to avoid losses due to a mistake.
If you are playing and by error you press "L" (Load) instead of "R" (Save) and lose the content of QuickSave, you will be able to recover it from the menu "Load State" being loaded the Slot Aux, where always you will have a copy of the previous QuickSave
