I patched my common5_en.pac with WiiScrubber, open it in Dolphin, doesn't load, FPS:0 VPS:60 SPEED:70%. Music still plays, what's wrong?
Download an unmodified common5_en.pac, and then compare the unmodified common5's size with your modified one.
How, specifically? Right click both of them and hit Properties. For it to work in-game, you have to make sure the modified common5's size is either the same or below the unmodified's common5 size.
I fixed before checked back here, heh heh. Oh, and I was modding Project M, so I did something similar. I Extracted the stuff I wanted to keep (char_bus_tex_lz77.pac, MiscData [70], etc). Then I patched them into Project M's Default common5_en.pac, and fixed!
