My Coff2omf is very old and I can't convert DX 7.0 libs. It crashes it. I tried borland libs but they didn't worked (They look very similar). It could be something I'm doing wrong too :

When I try to build something, there are errors when linking, something like "there is no directdrawcreate@12 function in that obj". Looks like it's generating wrong code !

Anyway, if you have the DX 7.0 libs precompiled for SC 7.5 or the updated COFF2OMF, send e-mail for me :
