C Compilers

2000-04-03 - GBDK - Gameboy Development Kit - Posted by: Jeff Frohwein
Check here if you're looking for an ANSI C compiler for GameBoy. It is based on the popular 'lcc' compiler that is a portable design.

2012-06-04 - SDCC - Small Device C Compiler - Posted by: Philipp Klaus Krause
Sdcc is a C compiler for standard (ANSI C89 / ISO C90, ISO C99) C, that can target the GameBoy CPU. An old version of sdcc (2.2.2) is used in the GBDK.

The Gameboy port has been unmaintained for some time, so there is no release supporting the GameBoy yet, but the current snapshots do support it. The Gameboy will be supported in the upcoming sdcc 3.2.0 release.

2000-02-27 - Small C Compiler for GameBoy - Posted by: Jeff Frohwein

A HowTo on dumping GB Camera images.

Compression

2000-02-27 - C64Pack - Posted by: Jeff Frohwein
Here is a decompressor for GB for the C64Pack compression program. It doesn't quite compress as well as RNC method 2 and takes about 2 times longer for decompression. Use the compressor in this package because the C64Pack compressor on the PuCrunch web page will not compress raw data.

2001-03-03 - GB Compress - Posted by: Jeff Frohwein
Sam has released v1.4 of GB Compress compression software for GB.

2000-02-27 - PuCrunch - Posted by: Jeff Frohwein
PuCrunch seems to provide better compression than RNC method 2 (on average) but it is about 5 times slower during decompression. Use PUCRUNCH -d -c0 inputfile outputfile. Otherwise Commodore 64 decompression code will be included in the packed data and the GB doesn't need that! NOTE: USE THE WIN95 VERSION. THE DOS VERSION OF PUCRUNCH DOESN"T SUPPORT OPTION -c0 THAT LETS YOU LEAVE OUT THE C64 CODE.

2000-02-27 - RNC v2.14 - Posted by: Jeff Frohwein
This is a compression package by Rob Northen Computing. It is free for non-commercial uses. For info on licensing it email Rob at rob@FILTER.markettrader.co.uk. (Remove FILTER.) A compressor for DOS & Amiga is provided and decompression code for GB, SNES, MIPS R4300, 68000, Atari Lynx, and 80286 is provided. This package has been used in commercial game titles for years.

2000-02-27 - GBDis v1.3 - Posted by: Jeff Frohwein
This is a disassembler for GameBoy that runs under DOS that I started writing back in 1993. Note that this program locks up if the ROM to disassemble is larger than 32k bytes. Use a program such as 'subset' to carve up a larger ROM into 32k byte size files. (Look in Misc PC Apps for 'subset'.) It has many options for output that should satisfy most peoples tastes. The output can be compiled with the Table ASseMbler (TASM).

2000-03-12 - Titan - Posted by: Jeff Frohwein
This is a Windows GB disassembler made by dox.
