Not the best at this. Got Homebrew, got braindump. The instructions are 1) With RomFS Builder, choose the ACNL romfs (dumped with braindump) and press "Go" 2) Download Delta Patcher: "http://www.romhacking.net/utilities/704/" 3) Open it, and choose the romfs create with RomFS Builder, for "XDelta patch" choose the ACWLHANSPatch.xdelta 4) Press "Apply Patch" and you get: Animal Crossing Wild Leaf Would the romfs be the .cxi file? 0004000000086300.cxi? If that is it, then with RomFS builder, I haven't been able to select it when searching the location that it is in. If the romfs is something entirely different, I entitle you the right to call me an idiot. Please help. I can figure out the rest. Maybe.
