no idea man its frustrating.. i've edited it perfectly no errors in code, compiled it, then removed the current missions.gsc from the patch compiled file (000000027.dat), and pasted the gsc zipped missions file perfectly fitting at the end with the yyyy part. and when i compile the 027.dat file and i make it compile into the patch_mp.ff file it seems fine and keeps the IW headers, etc.
black screen..
