Harry Mulder's Gameboy Development: Snippets


The following support for both GBTD and GBMB is available:

Gameboy Color Tiler (Windows EXE)

Screenshot from Gameboy Color Tiler This application will convert color bitmaps with more than 4 colors to a format which can be used by Gameboy Color; it is fully configurable and gives gradual results, so the longer you wait, the better the quality. It directly outputs to a GBR file, so you can use GBTD to do the final touchups and export the picture to your own format. This tool was not written by me, nor is it stored on my site; you can get it at Digital Infinity.


GBAU10.ZIP: Auto Update specification, version 1.0 - 5K (Word document)

Both GBTD and GBMB have a feature called "Auto Update", through which changes made in a tileset in GBTD are immediately reflected in GBMB. This feature is actually not restricted to my own tools; this document specifies how this process works, so that you can make your own tools respond in the same way.


PALRED06.ZIP: PALette REDucer version 0.6 - 41K (Dos EXE)

Screenshot from PALette REDucer This application will convert color bitmaps with more than 4 colors to a format which can be used by both Gameboy Color as well as the original Gameboy. It directly outputs to a GBR file, so you can use GBTD to do the final touchups and export the picture to your own format. This tool was not written by me, but by WolfWings.


GBRS9906.ZIP: GBR File format specification, June 1999 - 7K (Word document)

Contains the specification of the format of a GBR-file, as generated by GBTD. This document supercedes the document which is part of GBRDK.


GMAN039A.ZIP: Gameman Gameboy Tile & Map Optimizer/Exporter version 0.039a - 29K (Windows EXE)

Screenshot from Gameman Gameboy Tile & Map Optimizer/Exporter This helper application for GBTD and GBMB converts "standard" tile & map-sets to sets containing no reduntant tiles. It can even optimize using the flip-settings of the GBC. Next to this, it has some extra goodies which can be used to change tile and map-sets. This tool was not written by me, but by Jeremy Evers. It requires the MFC support library.


GBFONTA1.ZIP: GBTD Font Assistant version 1.0 - 9K (Windows EXE)

Screenshot from GBTD Font Assistant This is a helper application for GBTD; it let's you import fonts from Windows into GBTD, making them available to the Gameboy. Note that this application was made by Anaerob, not by me.


WC.ZIP: WarioCraft - 18K (ROM and GBDK source)

Screenshot from WarioCraft WarioCraft demonstrates how to show a GBC full-screen picture using GBTD, GBMB and GBDK. Although it is C-source, it gives a detailed explaination of some of the export-functions of GBTD and GBMB, so it is also an interresting read for Assembly-programmers.


GBMBCN01.ZIP: GBMB Converter version 0.1 - 132K (Windows EXE)

This tool will convert GBM-files made by GBMB version 0.9 and lower to the new format used by GBMB version 1.0 and higher.


GBMS9910.ZIP: GBM File format specification, October 1999 - 9K (Word document)

Contains the specification of the format of a GBM-file, as generated by GBMB 1.0 and higher (lower versions use a different format).


GBTDLIB1.ZIP: GBTD Library version 1 - 2K (RGBASM Source)

This library has functions which will load tiles generated by GBTD into VRAM. It can handle compressed or un-compressed, 4 or 2-color tiles and works correctly on a real Gameboy. This library requires GB4Real, so download that also if you do not have it already.


GBRDK10.ZIP: GBR Development Kit version 1.0 - 27K (MS Word Document and MSDOS EXEs)

If you are interested in doing more with GBR files, this package is just for you. It contains full file format specifications of GBR files. It also contains a GBR file information retriever and a compacter.
