Protoman's working on it.
Btw, Protoman, if you need help, I leeched those XA files DarkCloud uploaded but lost the will to finish, mainly because I'm not very familiar with the original music and gave up trying to time the songs.... however, I've identified a lot of tracks in case you haven't already done it. (I "analyzed" the XA files with PsmPlay 0.4, which seperated all the individual songs into individual tracks. The original format was eight tracks, with 4-6 parts in each track.)
Mega Man 4:
XA track 08 -- 01 Opening
XA track 27 -- 03 Title
XA track 20 -- 06 Game Start
XA track 26 -- 07 Brightman Stage
XA track 18 -- 08 Tordman Stage
XA track 01 -- 09 Drillman Stage
XA track 25 -- 10 Pharaohman Stage
XA track 21 -- 11 Ringman Stage
XA track 31 -- 12 Dustman Stage

XA track 30 -- 24 Last Boss
XA track 16 -- 25 All Stage Clear
XA track 29 -- 26 Ending

XA track 22 -- 01 Capcom Logo (part 1, the Capcom Logo)
