Hands down no$gba, but you'll have to pay to get the real debugger version.

MappyVM works well, but it's slow.

can't get it to work with Dawn of Souls for some reason

any alternatives?

all I really need is something that could add a breakpoint to whenever the code reads something off the rom (like text data) so I can find it in the rom and figure out how it's stored (I'm guessing (well hoping) that it's DTE)

btw.. what assembly "command" would I be looking for?

i actually have had almost no dealings with GBA and don't know the instruction set off the top of my head (so sorry as to not be of help in that respect), but have you had any experience at all with assembler before, or at least have a basic understanding of the concepts..? <img src=smilies/erm.gif>

oh, and technically, with the proper descretion and a knowledge of which area of the game you need to be working with (as in a defined range and location) you can find the same material with a hex editor. Obviously it's a bit more circumspect and archaic approach, i just wanted to point out that it's possible without a specially created tool.

If i'm recalling correctly a hacker from DESnet has been conducting some tomfoolery with the DoS rom
