I have all three, lemme test them.

EDIT: does this include the patches and CVS versions ? Or do I have to test with the original 0.65, which i'm not too fond of (because it lacks certain features I need).

0.65 first and then CVS.

Battlespire works fine for me in 0.65. At least the intro video, character generation and the beginning of the first level. This is after installing the Battlespire patch and ripping the CD to a bin/cue image and mount it with IMGMOUNT.

Wierd thing, thought, is that the game only detects "Warning: 31M RAM + Swap detected" in the beginning and not more even if DOSBox is configured for 63MB. While running in DOS on a real machine with 64MB, it will say something like "Good: 55+ RAM and swap detected".

I manage to run it with 45,000 cycles on the dynamic core on my AMD 3500+ which is somewhat playable with the low resolution and small game screen. I reckon it would be quite unplayable on a slower CPU.

Battlespire is only for people with CPUs that are less than two years old at best. My AMD 64 3000+ managed to run it on a nearly-playable level.

I'm hoping that my new Conroe E6600 will whipe the floor with it AND manage to run every other single DOS game I used to have speed-problems with (like Final Unity, which was still too slow to run in the 3D combat section).
