Since the Arena and Daggerfall versions on Steam are just emulated via DOSBox I was wondering if this is just emulated as well or has actually been ported to work on later Windows versions? I remember it being a huge hassle to get Multiplayer running via DOSBox which is why I'm asking....

Really??

When I try to play in fullscreen the game sutters horribly to the point that it becomes unplayable, are there any known fixes?

You CAN use a controller, but the "Partial Support" tag is misleading. You will have to set it up yourself through Steam controller config as Battlespire is simply running through DosBox. For anyone wondering who happens to pass through here, here are a few pointers about this game: -It uses outdated DosBox 0.73 and you'll need to update it to 0.74 otherwise OpenGL won't work with this release, and OpenGL mode is needed in order to access Steams overlay so that you can actually configure the controller! (...

Where did this come from?
