- * Drawing the Overworld
- * Tips by Zarby

- * 1) Find the graphics pointers (constants.h)
- * 2) Convert the 3bpp SNES data into PC 4bpp (Hard)
- * 3) Get the tiles32 data
- * 4) Get the tiles16 data
- * 5) Get the map32 data using lz2 variant decompression
- * 6) Get the graphics data of the map
- * 7) Load 4bpp into Pseudo VRAM for rendering tiles to screen
- * 8) Render the tiles to a bitmap with a B&W palette to start
- * 9) Get the palette data and find how it's loaded in game
