Holy crap how did I miss this thread? This is some excellent work! This only works for Stern SAM games? I would be willing to bet that Stern Whitestar games (pre Pirates) have a very similar if not the same data structures. So obviously you must rip the ROMs yourself until Stern comes out with their new system. How are the images compressed? Is the algorithm documented? I'm assuming raster-12 is a 12-bit bitmap format?
