SDL Source Code
TGB Dual is a Japanese Game Boy/Game Boy Color emulator. It was the first to support link cable emulation (through TCP/IP), later followed by VBA Link and then modern emulators. It is also available as a libretro core in RetroArch, based on unofficial Linux SDL port. The most common version which was translated to English by the author is ver. 7, but later an unofficial translation of v8.3.1 surfaced.
Ports and forks
The emulator is very old and obsolete nowadays. Still, there were recent tries to update the codebase and support new features. First, there was shinichiro.h's SDL port, which added no new features. After that came a few forks:
TGB Dual Kai
TGB Dual "L"
At first, a try at a pseudo-official continuation with ver. 9 release, the author named libertyernie soon found out about the Kai fork and added his enhancements to the newer codebase as TGB Dual "L". New features are a full translation from Japanese, Goomba Color files compatibility and mirror mode.
Source code on Github
TGB Dual supports plugins for additional devices. On the official site, there is a download for them. They are for the Barcode Reade, Pocket Printer and IR linking. As all documentation is in Japanese. The Barcode Boy implementation just generates random data until a valid barcode is accepted, as discovered by Shonumi in his reverse engineering work for GBE+.
