A small script for Aseprite that exports original GameBoy sprites/tiles to an Assembly or C/C++ format that can be used with GBDK.
Quickly turn your sprites into code that's compatible with GBDK. Just make your frames as usual, go to the scripts menu (File->Scripts), select GameBoy-Pattern, fill in the form and confirm then your code files should be at the desired location.
Sprites must be a size of 8x8 or 8x16 pixels.
Sprite palettes must contain exactly 4 colours and ordered from lightest to darkest.
All frames are exported from the active sprite in the order they appear.
Let me know if there's anything you want fixing or adding.
Install
Unzip the downloaded zip file and place the lua file in your Aseprite scripts folder.
