Quakespasm and Nehahra

Does anybody know why Quakespasm fails to launch Nehahra? I get the error dialog: sprites/explode1.spr32 has wrong version number (32 should be 1). Is Quakespasm not capable of running Nehahra?

Thanks

Nehahra uses a few special engine hacks and therefore requires its own engine. Regular source ports aren’t capable of running it.
There’s a modified and enhanced Glquake-based Nehahra engine by http://user.tninet.se/~xir870k/; Darkplaces supports it, too. And I believe DirectQ has limited support as well, but there’s no guarantee it’ll work without problems.
