use rcoedits extract all function.
delete everything except .mig files
rename .mig to .dat (because rcoedit will insert .dat file as it is otherwise it'll compress them)
replace all with rcoedit.
check ZiNgA BuRgA's thread about the rco format todo the necessary compression flag changes.

by the way i have madsoul's silk dream ready for 3.71M33 just waiting for fixed cxmb with paf/vshmain support.
