Trouble with ECWolf? For now, you can fix up DosBox

While ECWolf is easily the best way to play Wolf3D in current year, I've seen a couple people have trouble with it. While you attempt to work through that, you can also fix up Steam's garbage default configuration for DosBox so that the game will at least be the way the creators intended.

Make the following changes to both "wolf3d.conf" and "wolf3dc.conf"

Change "fullresolution=800x600" to "fullresolution=desktop" (this will prevent DosBox from changing your screen's resolution and messing up all your windows and stuff, a major annoyance for me)
Change "output=ddraw" to "output=openglnb" (this will make the game look crisp and nice, and not a blurry f*cking mess)
If, for some reason, the "output" change doesn't work for you, try "output=opengl" and change "scaler=none" to "scaler=normal3x" (or "scaler=normal2x" if that doesn't work). If it still doesn't work, then try "output=ddraw" with "scaler=normal3x".

Other DosBox games

Seriously, so many of these DOS games that are released on Steam have just two or three options that significantly affect the game's appearance and playability that can be fixed by one minute of editing a text file. In general, if you don't know what you're doing in DosBox, then a couple things to look for in any .conf file for a DosBox game are the above, plus the following:

Ensure that "aspect=true" (setting this to false will make games be stretched horizontally in fullscreen. I have no ♥♥♥♥♥♥♥ idea why it does this, it's not like it stretches to the entire screen, just most of it)
Ensure that "core=auto" and "cycles=auto" (makes sure that the game runs at maximum speed - looking at you, Star Wars: Dark Forces)
