When I load a game and it prompts to create a .SAV file, it creates a 0kb save file. I've run into this problem for every DS game I've put onto the R4. The 0kb save file gives me some problems, as whenever I go back into the game selection menu, the R4 freezes, forcing to me to delete the save file on my computer. I'm currently running YSMenu on my R4. Before this happened, I replaced some files (.dat files) on my YSMenu, so that WarioWare DIY would work, could this be the problem? Thank you!
