Export Sega Megadrive/Genesis tiles from Gimp

This is a plug-in for [Gimp](http://www.gimp.org/) for exporting images

as 8x8 tiles for Sega Genesis/Megadrive as asm68k source files.

### Installation

 - Copy **gimp_megadrive_export.py** to your Gimp plugins folder.  To find out

 its location, run Gimp and go to ``Edit > Preferences > Folders > Plug-ins``

 - (Skip if you're using Windows) Change file permissions by adding executable bit: ``chmod +x gimp_megadrive_export.py``

 - Restart Gimp

### Use

 - Make sure your image is indexed, with no more than 15 colors (may

   have transparency), use Image > Mode > Indexed.. to convert;

 - Go to File > Export As.., in "All export images" select "Asm68k

   files (*.asm)", click "Select File Type (By Extension)", then

   "Asm68k files";

 - Click "Export";

 - Click "Ok" in file-asm-save dialog box. You can choose whether to use

   COLRW macro (see below) or not, whether to merge duplicate palette colors,

   and choose export order of the tiles;

 - Done. If one or both of your image's dimensions is not a multiple of

   8, the plugin will show a dialog box informing of unexported pixels.

COLRW is an asm68k macro that I use to improve readability of exported

palettes.

With it you can see palette RGB values (0 - 7) in the code, instead of

color components packed into hexadecimal words.

### To do

 - Tile optimization: add an option to skip repeating tiles
