Homebrew Switch Buttons in GBA - MODE

[freshness]

Hey, few days ago I got my 3in1 Ez expansion pack!

I love the features, but that´s not the topic. What really sucks, that you can´t switch the buttons. Look, I mean, its so fucking annoying to hold B for running and then press A for jumping. It would be much easier to hold Y for running than pressing B for jumping. Maybe you don´t get my point, I know, its a small problem and maybe you think: what a jerk...but fuck it I want to hold the Y-Button, playing would be so much smoother for me...

So, I want to know if there is a patcher or something like that for gba-roms to realize my wish, because I couldn´t imagine that a homebrew prog can handle this...maybe someone can write a little program, i would do it by myself, but I have no idea of DS programming...

Please, don´t insult me, because, I´ve found nothing about it, maybe I´m the only person on this planet complaining about the A/B buttons...

Unfortunately, it's not possible. When the DS goes into GBA mode, those two buttons are disabled and have no function. I think it's hardwired that way and cannot be changed. I've always wished you could use the x and y buttons in GBA games too since the a and b buttons tend to get more use than the rest of the buttons on the DS.

Basically when you load a GBA game, your DS goes into GBA mode... That is, it uses a GBA BIOS built into the DS... This BIOS acts just like a regular GBA and therefore can't see the extra DS hardware. There is no way to modify this BIOS since it's on a read only chip so there is no way to accomplish this.

Damn. I was thinking of a hack to have X and Y be turbo A and B.

While software-wise it's imposible (unless we somehow got a GBA emulator), hardware wise it's pretty possible. You'd have to make some modifications, and put a switch to change Y-B for A-B. Of course, doing such a thing isn't easy, but the alternative is there.

There actually is a modchip for the DS that does exactly that. I haven't seen them switch A/B to Y/B though, which I agree would be very beneficial.

Actually, they would have to change it to B/Y instead of Y/B, or it would become weird as heck.

I was more referring to the buttons themselves, not the order, but yeah of course that's what I meant.
