Re-scaling low-res stages to run with hi-res MUGEN

[Sablicious]

I take it one must re-scale low-res stages (& select screens for that matter) to run correctly with hi-res version of MUGEN...?
I transferred my existing mainly low-res stuff to the hi-res patch, but most of my stages (with the exception of the hi-res stuff) ended up all over the place (ie. axis off-sets incorrect etc).

Can low-res stuff run with hi-res MUGEN?  If so, how does one re-scale the former?  Also, if the method is protracted and laborious, is there a patch (a la the DOS2Win thingie) which facilitates the process?

Thanks.
