LET THIS BE A WARNING TO ALL OF U CAUSE THIS MIGHT HAPPEN TO U(ON R4) My pokemon HG rom on my r4 got corrupted not my sav file. its because i did not know that it was possible for the sav file to get to big. So i need to delete the ROM but i cant because when i try accessing the 'game' folder on my computer it says its corrupted folder. so i try deleting it on my r4(on my ds) but the game is not showing but when i use the ysmenu it shows, when i scroll to select the pokemon game and going to press the X button to delete it it freezes. it freezes as soon as i put to bar on the game!! so if i can some how delete the game WITHOUT DELETING the sav file i would be happy. (i know how to expand the sav file to 1 mb now) or if i can somehow get my sav file to my computer that would work... maby wireless transfer(if possible) So try ur best to help me i would really appreciate it!!
Copy the whole card to your computer, and se if the gamefolder still is corruptet. If not - format the card, put the firmware back, a new ROM for Pokemon and then put the savefile from your computer back on the card?
