Hell world

Because this LD is amounting to an excuse for tech work, I have a total of five graphical assets in the game, but I have to build up most of the systems to load and draw them still. Shown is the existing Galapagos testbed, which can draw text and play a sine wave, with a sprite artfully placed on top of "hello". I just did some code to remap palettes so that it draws the sprite correctly using the Galapagos palettized shader...and next up is adding some colorkey support so that sprites can overlap each other.
