Progress is going to be momentarily paused. Last night I had my first experience at live sound operation and recording. It went pretty well, until my portable rack got stolen. I had most of my recording stuff in there, along with most of my microphones and the audio interface. So, right now I can no longer work. It's gonna take a while to replace most of my equipment, since all the studio gear is imported (there's no national audio industry here). Anyway, I don't like bothering other people with my personal issues, but one of many things I'll have to sell is my home PC, my main development machine. I'll migrate the project to my studio workstation, and resume work when this setback is taken care of. In the meantime, here is the Metroid Map example I promised. If you are into GM programming, and need a simple and effective map, you might find it useful.
