I was playing Mother 1+2 on a NDS Lite with R4 card and EZ-FLash 3in1. I had loaded the Mother1+2 GBA file into the PSRAM of the cart. After exiting, I noticed that my .sav file, located on the microSD card, was only 16 bytes in size?! I tried a few other games in PSRAM and they leave save files of irregular sizes ranging from 16 bytes to 8.02 KB. I am able to restore my game normally on the NDS+R4+EZ3in1 but the save file does not work on visual boy advance. Does EZ3in1 store save files in some strange way when you are running the game from PSRAM? For a game in the NOR, I can use GBAtool to extract a usable battery .sav file, no problem.
