So ive been working on custom 'dlc' for guitar hero wt, and i ran into a few problems. First, when i did a fs dump, and tried to directly copy the tmd, app cert... it gave me an error that said that i needed 12 more app files. Well i assume that this is for the new dlc, which nobody currently has. So i edited the tmd file to only load the first three. (00000000.app, the banner,00000001.app and 00000002.app, the song) well now the wad compiles correctly but it gives me the error -1022, which sombody on a forum said was a sha1 error, however i double checked all that and it seems to be ok. my only guesses left would be to change the index or type of the app files in the tmd. Anybody else ever try to edit the tmd like this? is there a app that does this? also would any of the random variables in the tmd change anything (like boot index or version)
