As I've said elsewhere, the DSSSL stylesheet itself should work fine in OpenJade under Windows, but I'm not in a position to hand-hold with this. If you get OpenJade up and running, it should be straightforward to get it working on jEmplode's output. It's possible that you may need to tweak one or more of the environment variables that control it, but I would expect that the Windows binary distribution will explain what's needed, and possibly even do it for you.

If you get as far as error messages, post them here and I'll do my best to interpret them. If you get further, and now have pretty RTF files, definitely post here, so others know it can be done.

BTW, the makefile isn't necessary; it's just a convenience for those with a suitable environment. The only absolute prerequisite is Jade or OpenJade.
