The last time I played with raycasting in SGDK, there were some serious bugs that I couldn't work around. So I gave up and deleted the videos. This version is still based on Lode's tutorial (lodev.org/cgtutor/raycasting.html) for the DDA and GameHut's mirrored texture code to draw the columns.
I've replaced as much multiplication and division that I can with LUTs and tried to avoid un-necessary operations when drawing the columns. Frame rates have improved from 6-15 FPS to 15-20 FPS. If I can get a few sprites in without killing the frame rate I'll try getting it to work with the Retro.Link netcode. If that doesn't work, it'll end up in some other game.
