Is it possbile to traceback the address if I got AR code?

[doniface]

The game: Chrono Trigger had a protection for dump rom playing, however it still be found the solution, just using these codes:

0204E364 E3A00000
0204E368 E12FFF1E
0204E6c4 E3A00000
0204E6c8 E12FFF1E

and the protection will be passed, however I would like to know if it is possible to know the source addresses above in the rom? because I do not want these codes always keep refreshing since it should be some arm command lines only.

I tried to watch the ram address datas vis HasteDS, and searching them in the rom, however the search did not find any matches, for example the address 0204E364 to 0204E368 contained 30 40 2D E9 5C D0 4D E2, but these strings did not exist in the rom...

So anyone can help to find the original addresses in the rom? or it is impossible to find out? why?

It could be that it is compressed in the rom. This tutorial might help you out.

Try using no$gba and emuhaste instead?

Both HasteDS and Emuhaste had the same data in those addresses..
