    He just continually pressed the Home button which somehow made the fb start dipping for some reason. In the description he made it sound like it only happens with that game specifically.

    It'd be cool if someone can confirm this as a regular issue or if it's exclusive to that game and region. After all the European version of FE is 32MB while the American one is 16MB, it doesn't give much of a reason for the problem but it's one huge difference between the those two versions.

    I didn't see it do anything, what is supposed to be going on here?

    European version is bigger because it has probably 5 to 6 different languages.

    He pressed the home button then back and the display of the game started to go up and continued below, like an old damaged vhs tape. The game however was still playing correctly.

    I said that because 32MB GBA games tend to be problematic compared to 16MB ones.
    -The emu Nintendo uses for GBA demos cannot load 32MB roms.
    -RA originally gave a stackdump when loading 32MB roms.
    -Flashcarts use a different chip for 32MB roms(NOR memory).

    You are right, the multiple languages are the reason for it being bigger but it's irrelevant.

    Well, I'm completely lost on what the problem really is, and the video doesn't show much of anything. It's not a buffer overflow or anything that can be used to hack the system, so what is the point of this? He makes the screen go lighter & darker by hitting the home key over & over? Only happens is that game? Big whoop. Doesn't mean crap.

    Having not played the game, it wasn't apparent to me. And once again, so what? Explain to me how this matter in the slightest? Miss placed video, wow.

    I decided to watch the video again, and now that you pointed it out, yes I noticed it, but having not played the game, it wasn't noticeable at all. Maybe it was the crappy camera work, maybe it was because I haven't played the game, but it's not really noticeable unless you know what you are looking at. He might of explained it in his video, but who listens?

    Screen is stored in a memory location. For whatever reason, which HOME is hit, the starting point of the redrawing the screen isn't getting set back to the top of the screen, it's going to a different location. Since there are no garbled graphics on the screen, it most likely not overwriting any memory, or grabbing other parts of memory, it's showing what is there, it just starts the drawing at the wrong location.

    Since I am not a 3DS developer, I do not know how the swapping to HOME works, so I can't say for sure where the error lies, but since it only happens on this one game (apparently), it's probably some minor error that a compiler doesn't catch.

    But as I said, not useable to hack the system generally.

    my dad works for nintendo.
    i didn't played a fire emblem game. (just tried the 3ds demo) so i was in the same shoes you are.

    OP didn't mentioned using this like hacking, its just a interesting bug...
    can't anyone point out a bug without everyone talks about "hack" the console...
