Hacking ROM Hack Is it possible to create a Memory Patch to replace a text string in main.dol?

[Louis Miles]

I am looking for a way to replace a text string in the main.dol executable using a memory patch (for a Riivolution Mod). However, I don't have much experience with such patches and couldn't find anything that could help me. All I want is a patch for Riivolution to replace the text string "StageData" with "LevelData" in main.dol.

Are there any tutorials or something like that which could help me with this, or would someone like to help me with this?
Is it at all possible to replace a text string with a patch?

Thanks in advance
