I have a small problem with my EZFlash 3-in-1 when using the latest version of GBA_ExpLoader with an R4. The PSRAM, rumble and memory functions work great- however, when loading games into NOR more often than not the program will freeze and I am forced to reboot the DS. It always freezes at 94%, 95%- about a second away from completion. Interestingly, it does successfully load the game to the cartridge but does not load existing save data- nor, in fact, does it register that that game is present (so, I can use the game as a normal cartridge, I can even save, but it will not then backup it's save data when I switch to another game in NOR. At the moment, it is stuck as thinking that "Advance Wars.sav" is the revelent save file, as I manager to successfully NOR flash this game. However, Castlevania Arai of Sorrow is the actual game on the cart. I am not sure, but I think it is writing my Castlevania save data to the Advance Wars file. This problem occurs with a combination of game, SRAM patched, trimmed, both or none. Larger files seem to do it more but so does Mario Kart. It's not a major problem. Every part of the PSRAM playing works fine, and that's all I need. It just effectively removes my ability to use the 3-in-1 independent of the R4, in, say, my GBA. Any ideas why this problem might be occuring?
