There is a feature in Emulation Station to do precicely that (didn't know until now !). Never tested it but it should work fine :

In Emulation Station, press START to access the MAIN MENU.

Select the second menu : GAME SETTINGS

From there, turn on the auto save/load option :

The auto save/load option allows you to auto save a savestate when you exit a game, then reload automatically this savestate when you restart this game. Once the game started, and the savestate loaded, if you want to return to the title screen of this game, use the special command reset. You can enable it by emulator in recalbox.conf

WARNING : I think this option will be ON for every games / emulators included with RetroArch, instead of just the games you want it to be turned on.
