It seems like the autosave function doesn’t work during shutdown.
I set the device for 30sec sleep + shutdown and the save doesn’t work.
Open a GBA game, use the power off button to go to sleep mode
When I get back it loads to an older auto save (since the autosave didn’t happen). Changing the sleep option to instance shutdown auto save seems to work (not sure if it’s consistent yet)
Issue is very similar to this Auto save sometimes fails when device shutdown after sleep x amount of time where I didn’t see any real solution there.
I’m using the TrimUI brick hammer
