Finally managed compile descent on my C1000 running pdaxii13 5.3.3.
Remaped save/load keys to O,P from alt+F2 alt+F3.
Other keys you can remap in menu.

You will need also descent.hog and descent.pig files from game
(no problem to find on net. If still problem, PM me)

Best played zoomed with usb mouse.
d1x-rebirth-sdl -menu320x240 -tmap quad (for 320x240)
d1x-rebirth-sdl -tmap quad (for 640x480)

When you are playing in 320x240, game is so fast that you won't need -tmap quad parameter.

Someone could package it properly ... just giving away binary ... thnx
