Hey folks, I'm sorry to bump a thread that's been dead for 3 years, but I've been having the hardest time finding instructions for beginning to make Smash 3DS hacks. Every tutorial I find is outdated or terribly-written, or both, and I've been searching and asking for over a week. Hoping somebody can point me in the right direction, please and thank.
OP's guide says to use HackingToolkit9DS, but it seems as though, at the time it was written, HT9DS produced the RomFS and ExeFS in a different manner than it currently does. I've tried using the programs in this guide with ExtractedRomFS.bin, DecryptedRomFS.bin, the /ExtractedRomFS folder, and even the dt and ls files contained within, and none of them worked.
I'd like to try making some in-depth mods, but the first one I'm planning could be as simple as swapping a couple filenames in the DTLS, which means I could probably just repack it and go.
