Various helper scripts that compile the sprites in FSROOT/PICS/SPRITES.
To compile the data, run make LOCAL=1; this compiles the various configuration and data files in the data folder and produces an out folder with the compiled data files.
Note that the actual pictures are not included and need to be supplied separately. In
particular, you should create a data folder with subfolders pkmn, pkmn-back, and
pkmn-icon containing 96x96, 96x96, and 32x32 sprites of the mons you wish to include;
the files should be named %hu[f][s][f][_%hhu][f][s][f].png (as an example, 41sf.png is the sprite of shiny, female Zubat; 050_1s.png is the sprite of shiny Alolan Diglett.)
