Autosave feature.

Played all the maps and was doing sign hunting. Forgot to save manually and lost all progress.

QOL Feature.

[JackandBeans]

1.1.7 is out with Autosave: https://github.com/JackandBeans/Snap64Recomp/releases/tag/v1.1.7

Turn it on in Options > Game. From then on the game saves by itself every time you come back to Oak's lab with new photos or progress. It's off by default, so the game still works like the cartridge until you turn it on.

Sorry you lost all that progress, and thanks for the idea!
