The assembly code will assemble as-is for a 32-bit environment. It will not be
particularly fast or efficient, but it doesn't need any conversion.

The only stuff that would need conversion are graphics routines and the like.

If it runs fine in Windows 2000, it will run fine in Windows XP. You may have to
fiddle with it, but I've yet to find a program that breaks my claim.
