Last night I was playing Policenauts and made it pretty far. After an ingame save and closing I came back to it today to load the game only to not have it load my game at all. Is this a known issue, or am I not using retroarch correctly?
Your save probably never got written to file. By default, RetroArch only writes saves to files when you exit cleanly (e.g., by using the ‘quit retroarch’ option from the menu).
Whenever I want to quit, I just go into the menu and use “close content” to shut down the game. This will write the save to file and then I can exit however I please.
In settings > saving, there’s an option called “SRAM Autosave Interval”, which will flush the save to disk however often you set it. Something like 10 seconds is usually sufficient and won’t put too much strain on solid-state storage, but you can set it lower if you want.
