I've been playing the Chex Quest 3 wad for a while, but I'd like to play through the originl again, for old times sake. But, I can't seem to find the original wad. It's posted in the downloads, but whenever I download it and try to open the zip file, it says that the file is invalid.
The Chex Quest Gallery (http://gallery.xboltz.net/downloads/) is probably the best place to go for downloads.
(it seems all things in the downloads are dead, ATM, but the gallery is still good)
More specificly, you probably want the compact (http://gallery.xboltz.net/downloads/Chexquest.zip) package.
Either run the WAD in ZDooM, or load up DOSBox and play.
Awesome, thanks!
