Doraemon, I'm not quite sure what the problem is, but if you're still experiencing it maybe you could make a Lha of the Backbone directory with all the files, send it over and I could have a look, try and compile it myself.
I would like to put together a collection of blocks and sprites that people are free to use in their games, so currently Cammy and I are working on a game which uses these graphics as a demonstration of how they can be used, then we'll release the game and all the free graphics, and the Backbone files for anyone to have a look at how it's all put together.
Inspired by amiman99, we put together this first level of Super Mario Bros but it's not really feature-complete, it was just for fun. We just copied the level layout from the original game, all I did was remapped the tiles and sprites to a single 15 colour palette.
