Gameboy Tile Designer Logo

Welcome to the Gameboy Map Builder !

With the Gameboy Map Builder ("GBMB"), you can make maps which you can incorporate in your own Gameboy productions.

Some of it's features are:

GBMB in different sizes.. GBMB gives you a large (1024 x 1024 tiles max) canvas on which you can draw tiles made by GBTD, which supports any tile size and color GBTD can handle. This can be used for map or level-design. Next to that, this canvas can easily be used for other purposes, like still pictures. Options like five levels of zooming and a fully resizable window help you with looking at your design in any way you want. Also, with build-in support for Gameboy Color-extensions like vertical/ horizontal flip and 768 tiles per tileset, GBC-development is a snap.

Using properties with GBMB.. GBMB let's you define your own properties, with which you can manage extra storage for each location of your map. GBMB will even keep track of default property values for each tile, making usage of properties a lot easier. These properties can be exported in a format and size of your own choosing.

Direct export to various formats.. GBMB exports directly to RGBDS Assembly-source, Objectfile ("RGB1"), GBDK C-source, TASM Assembly-source, ISAS Assembly-source, and flat binary. The form in which you want to export is fully definable. It even generates include and header files, which state not only the labels, but also general info about the exported data. Also, all settings you make are saved for each individual map, so you don't have to remember which settings are appropriate for which map.

GBMB is Freeware !

The Gameboy Map Builder is Freeware; you are allowed to use it in any way you want, without paying me anything. You are also allowed (and encouraged) to distribute this software, as long as you don't receive any payment for it. If you want to link your home page to GBMB, be sure to link it to this site, not directly to the downloadable file, as updates will receive different filenames. Keep in mind that you use this software at your own risk; any damage which might occur, in whatever form, is your own responsibility.


GBMB operates under Windows 95, 98 and NT4. GBMB does not have to be installed; simply download and unzip the package below and start GBMB.EXE. Keep all the accompanied files in the same directory, and associate .GBM-files to GBMB for maximum enjoyment. Check out the included README.TXT for more info. Remember that GBMB only works with tilesets made by GBTD, so if you don't have it already, make sure to download it also from this site.
