Stage troubles

[Vucious Creed]

Hey everyone.  I'm a newb in mugen and I'm trying to upload stages into my WinMugen engine.  However, some stages are not working propery.  I get this particular error message:

"Error message: BG error reading stage/[insert name file].def
Library error message: Error reading sprite stages/[insert name file].def"

I don't know if these particular files are for MugenDOS rather than WinMugen, the coding is wrong (doubt it), or something else I don't know about.  These are the stages that I am having trouble with:

The Train Stage (CVS Pro) by LenaShock or CharlesProphony (whichever, whatever) 

Dr. Doom's Stage
Iron Man's Stage
Magneto's Stage
Thanos' Stage (all from Marvel Super Heros and created by Juan Carlos)

A Japanese Street (KOF '99) by NeoGouki

Matrix Revolutions: Final Battle
Flight on a plane (both by kusanagi ky0)

Bar Matrimelee/Saizo's Stage (Power Instinct Matrimelee) by Vampipe

Tenkaichi Budokai
Satan Stadium (both from DBZ2 Arcade and created by XGargoyle)

This is an awful lot of crap to deal with, isn't it?  So if someone can tell me what the problem is and if it possible to fix this situation, or each stage has its own individual problem, please let me know.  I really want these stages.

im having the same problem, i ripped all stages from a DOSMugen game and now 90% of those stages dont work in my winmugen.

Is there a program to convert dosmugen stages to winmugen stages?

Thanks in advance

I just fixed it, just go to the stages .def file and look for something like this:

[BGdef]
spr = stages\budou-dbz2-tarde.sff

change it to

spr = budou-dbz2-tarde.sff

Your welcome (i had to change about 60 stages lol)

That works, you can just change this:

[BGdef]
spr = stages\budou-dbz2-tarde.sff

To this:

[BGdef]
spr = stages/budou-dbz2-tarde.sff

Isn't a shame that fixing stages was as easy as changing slashes? 

Anyway thanks for all the help, every stage I fixed now works.
