16Tile

16Tile is a tool designed to help creating tilemaps for the Sega Genesis/Mega Drive. The tool features a simple user interface focused on tilemap editing as well as different paint modes: Tile Mode, Palette Mode, Priority Mode and the Tilemap Painter, which allows the user to paint directly into the tilemap.

This software is meant to be used with SGDK, a free development kit made by Stephane Dallongeville (https://github.com/Stephane-D/SGDK). The palettes, tilesets and tilemap can all be exported into the 8-Bit PNG format and then imported into SGDK through Rescomp.

16Tile comes with an SGDK sample to show all the main features of the tool. The ROM can be found in the Sample\bin folder and the source code in the Sample\source folder (which also includes the 16Tile project).
