Hey, not sure if anyone else noticed this but there's a gold mine of cool stuff for this game here. A mirror of this stuff on Wayback can also be found here incase the site goes down. Also, if you're a non-Windows user (like me) is worth mentioning that some of the utilities require Windows and will refuse to run in DOSBox. The ones that do work in DOSBox are as follows: DUKEEDIT (2.0 only), DN1MOD, SNDPLAY & TEXTRACT (and of course the included user levels). I also couldn't help but notice this game runs at a messily 15fps. Well I found this. Check out the bottom line, implies the fps can be increased. I'm not an expert at hacking so I'm gonna leave that to someone smarter and more experienced than me. Anyways, enjoy.
