16 colors and 8 colors modes for the SCI0 and SCI1 PC-98 games. The 8 colors modes are new, the 16 colors mode is basically the pre-existing mode, just with some minor fixes (palette, font drawing, etc.). The final goal is to get rid of the upscaling inside the engine, but that will require more work on the other game versions that depend on it.
