* 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
