So I just watch for the occasional "new" thing I can do with my GP2X and came across some posts about hires conversion for Doom. Since I run (and play) dozens of pwads I thought it would be really cool to get back to the original ... but better. Here you can find a texture pack that gives Doom a WOW factor on the small screen. It has never looked so sharp (literally). unzip the pak3 file (I used zd-dhtp-20100114.pk3) and move the flats and textures directories into a new Hires directory and re-zip and rename to pk3. Then load your doom2 with a -file zd-dhtp-20100114.pk3 parameter and ... wait. It takes a while to load.
Played part of the first level. Holding up nice.
