Hi Mark! I am taking part in a game jam with a small dev community in Spain and will use Blitz3D and Maplet for it (it's a retro compo, most of us are using "legacy" technologies, and I like the idea of the game working on Win9x).
Do you happen to have the specs of the .maplet format by chance? I'd like to extract the information of the lights from it to use it in the game.
BTW, I love playing with Blitz again! I used it for a long time a couple of decades ago, used to visit BRL's forums under the nickname "Jedive".
