Unfortunately doesn't work on a real Master System, it gives an error (0x30). Tried on a MegaDrive (my cart runs also Master System roms) but doesn't work either

I had somebody else report a similar issue and it turned out that their particular type of flash cart was throwing an error because it didn't support the loading of Master System games above a certain size; is it possible this is what you're running into as well? The game is 3MB, which is to my knowledge the largest SMS game ever released but is within the theoretical maximum size limit.
