map_put_tile
From ArchaicPixels: HuC and PCEAS Documentation
map_put_tile(char x, char y, char tile); [ 3.20+ ]
Modifies the map data (sets a map element to a new tile ID), but
works only when the map is stored in RAM - ie. a Super CDROM game
which is loaded into RAM, and executes there. 'x' and 'y' are
specified in the same units as map_get_tile() (ie. pixels, not tiles).
