As the title suggests, I'm trying to edit a text string in Mii Maker. This is my first time trying to edit a ROM like this, so if I'm making myself look like what could be described as clueless then it's exactly what it looks like. I have a vague idea of what I'm doing wrong, but I'm just looking for some guidance, so here's what I did step-by-step. Dumped Mii Maker using Braindump. Used ctrtool to extract the romfs.bin (and exefs.bin but that doesn't matter I think, didn't do anything with that file). Decompressed ../romfsdir/Message/EU_English.arc using EveryFileExplorer. (Here's where I believe I screwed up astronomically) Opened the decompressed EU_English.arc file in a hex editor. Found the text I wanted to edit. Yes, I ADDED bytes to the file. Compressed EU_English.arc again. Used HANSHelper to build the modified romfs with the first 0x1000 bytes trimmed. This didn't quite work and Mii Maker failed to boot using this romfs file, so I'm hoping someone could help point me on the right path at least? Thanks in advance.
