Blade of darkness lighting

Anyone got any tips on how we can make lighting/shadows in Dungeon Maker like the lighting which was done in Blade of Darkness?

Also anyone know of any tips about doing varying levels of specular highlights and bump maping on a image in blitz3d :) (Wanna make nice walls :))

Thanks for any advice

The only thing I've seen that can do shadows like this in Blitz is of course Mr. Swift's shadow system.

Swift's Shadow System?

Sswift to you. Uhh, look up any post of his and click on his sig. It's all there...
