Hi guys, Im kinda new at posting. Ive been makin my own nsmb hack lately. Recently i encountered two problems that i couldnt find the answers to anywhere.. I recreated world 1 level 2 area 1 and on desmume it runs great. But when i run it on my acekard the level has a red square around it with a red line in the center.. I figured if it ran great on desmume why would it mess up on the flashcart. Plus my other 2 levels have been edited wayy more and they look and run perfect. My other problem is this. I edited the tower and everythin was perfect. One second it was running perfect on desmume. The very next second i tried playin the level and now when i go into it. The screen is just black! It was literally from one second to the next. I figured i would export the level and import it into a clean rom. But it still does the same thing for both levels =( Could someone help me out. Im pretty new at this stuff and was just doin it for fun, but i really started to enjoy it. Only to have this crap happen lol. anyways if u guys could help me recover these levels & teach me how to recover files when this happens it would be awesome! oh yea. also wut are the: "name of rom".ds1 or ds2 files??
