ROM Hack Control change for pokemon HG

[GOGOROBO]

Is there a hack/mod for HG so that the touchscreen can be used to move instead of the D-pad?

I really need it, I broke the trace going to the down button on my DS lite while modding it.
I already know how to fix my DS it is just a matter of money; I'm flat broke.

Is it easy enough to hack it myself? I have very basic knowledge of hex editing, mostly changing small values or replacing a few lines with premade code.

Just use the NO$GBA debugger or something like that, find out what happens when you try to press the D-Pad (on the emu), find out what happens when you try to press the touch screen (above, below, left of, and right of the char.) and make an AR code that remaps the memory addresses!

Much simpler than it sounds, I THINK.

Thanks for the tip. I'll post whatever I find here.
If anything.

--EDIT--

I'm using IdeaS debugger at the moment. Is there any certain part you would suggest to look in?
Like the ITCM or DTCM, external or internal WRAM
