GENERAL Hacking tools for GBA?

[toni15538]

Hello.
I want to hack Warioware inc. and Warioware Twisted. I want to change sprites(or import from myself) and swap texts and musics.
I searched for tools, but they are not working, or for hacking Pokemon games.

I want some tools, like Crystal tile 2 and the tool 'pack' from NSMB editor and MKDS course modifier/editor, but for GBA roms...

Well, you see GBA games don't actually have a filesytem, so there are no general tools for editing GBA games. I guess you could try to locate the graphics manually, but it would be pretty hard to put the image back into the rom(assuming you can even extract it), since you'd have to manually patch all offsets in the rom(and again, that's if you are even able to extract it). If you want further info on that check out this article
Editing texts can be easy, unless the game uses a custom character table(which it probaly does), if not you can just simply search for the text string in the hex editor.
As for the music if the game uses Mp2000(aka sappy) engine you can use GbaMusRipper to extract the music to .sf2 sound fonts and midi's, which you can alter and then put back into the rom(though I'm not sure how).

The DS guide includes GBA stuff because it is easy

Similarly Crystaltile2 has all sorts of support for GBA graphics formats (the GBA4bpp and GBA8bpp formats that DS games use being named for a reason), compression formats and a disassembler as well all the other tools (relative search, script search...) that CT2 has.

Otherwise what CHEMI6DER said.
