I have r4ds, Supercard lite, but I don't think I use them in 100%. I mean, they are great for commercial games but I want to play with homebrew software. Unfortunately everything is so complicated to me. I tried to make Wolf3d and descent games but I failed. I don't know how to make it working. So, the only things that work for me are prdoom (Doom port) and Lemings. Perhaps someone would help me by sending one big archive with all this programs working prepared for R4ds or SCL? I don't have time to figure it out by myself. Thank in advance.
