Does anyone know if this Eduke32 ( http://eduke32.com/ ) works with the GOG version of Duke Nukem 3D? It appears to want installation files from the CD in order to be installed (specifically the DN3DINST or ATOMINST folders) and I'll probably buy Duke from GOG if it does.
Thanks!

It will work for sure, using Eduke32 and the GOG version of Duke 3D myself.

I still think it's amazing I can run Duke3D in 1920x1080, and nothing looks stretched at all.

You just have to dump EDuke32 into the DN3D directory and it will automatically detect the game and do everything itself; the installation files aren't needed.
EDuke32 uses a completely new renderer--the skewing limitation the original engine suffered from no longer occurs, so it can support any given resolution (this is most obvious if you have mouselook enabled and compare it to mouselook in the DOS original).

Awesome, thanks!

The easiest way to make EDuke32 work is just to copy the DUKE3D.GRP to the EDuke32 directory, nothing else is required.

Eduke32 works on the same principle as other DOS 2.5D FPS games, that all you need is the original data file, which contains all the game data. Just grab DUKE3D.GRP and throw it into the source port's directory and you're good to go!
Of course, I like playing it in DOSBox, to retain that old "DOS" feel. But I'm weird like that.

Get the HRP it works great with EDuke and makes everything 3D with new guns :D

It's ugly as shit, though. (Gun/enemy models)

I don't think it looks that bad.

I've just downloaded Duke Nukem 3D from GOG and have tried running it theough eDuke 32 for Mac (sorry, I'm using a mac) but really can't find the .grp file referred to elsewhere. I've tried the 'show contents' option when clicking on the Duke Nukem icon but I cannot see it anywhere. I've also checked the 'show hidden files' approach but really cannot see it. Feeling a bit think now but would be grateful for any assistance.
