Save data problem

[Ultimate warrior]

Hello. I'm trying to create a Super Mario Advance 4 save with the E-Reader Levels inside, so I can play them on the PSP. I've been using this video on youtube.



Anyways, I can load up the ROM fine, but when I try to start world 1-1, the emulator crashes and shuts down. Then, whenever I try to load the emulator, it says "NO GBA has recieved an error and has to close. We are sorry for any inconvenience." I know for a fact that it has something to do with the save file, becuase whenever I delete it, the game loads up fine (then crashes once I start world 1-1 again). That, plus I do change the save type to the same name for the E-reader file, and "access saved data" doesn't appear. Any help please?

Could i use a save from this website as an alternative?
