All TTF files are identical with the ones from SP2 RC [previous edition] = these install as part of TTFPAK.EXE:
http://www.mdgx.com/add.htm#TTFSERVICES [used in SERVIC9X.EXE + SERVICNT.EXE] = also identical.
L3CODECP.ACM = identical version with XP SP2 [WMP9 for XP] but different file size [?].
Tested it, doesn't seem to work differently in any way.
If anybody else wants to test this new L3CODECP.ACM file and compare with the other one, please let me know.
Otherwise nothing else I've tested works with Win9x OSes.
HTH
