I've recently been directed to this hyperspin site:
http://hyperlist.hyperspin-fe.com/index.phpwhere you can download ROM lists for other (non-MAME) systems, and noticed that the DOS XML is empty.
I just happen to be involved with a very large DOS collection project and thought that I might be able to help getting the DOS visibility kicked up a notch. This might also bring more users into my DOS project so I think it's a win-win.
I am not currently running HS, so I don't know the technical hurdles of getting games to launch using it, but I can absolutely provide "roms" to experiment with, .dat files, and can auto generate XML that should be HS friendly to build a list from.
Pop me a PM and maybe we can help bring another platform up!
