Code:
xcopy /b brawlmods\projectm\stage\melee\ ssbb.d\files\stage\melee\
and change GCTSIZE to 9400
I am trying it now and will report back... if it won't work, then I guess I gotta add every single file manually >.<
Edit:
Alright, it worked

I am now playing SSBB: Project M 2.6b with 77 Stages and modified music as .iso via WiiFlow =)
Great topic! There were some really helpfull posts in here, reading through those 5 sites was worth the trouble

Now we gotta wait for Project M 3.0 (December 9th)
