This is a micro-kernel with the following features:

• Pre-emptive multitasking: (Up to 255 threads.)
• 95% efficient context switching.
• IPC via Semaphores: (Up to 255 semaphores)
• Puts CPU into sleep mode when no tasks are running. (Low Power)

Sitting under threadlib is a single service called gblink.

This implements a simple bitstream engine which can be used as is or used to implement other higher level protocols.

The following protcols were built into the bitstream.

• A simple UDP style datagram packet protocol.
• A simple TCP style stream protocol (under construction).

The protocol is designed to reliably "trade" items from:

• GB to GB
• GB to PC 
• GB to PC to PC (via network) to GB.

This is written in 100% assembler and is compiled using RGBDS (Rednex GameBoy Development System) under linux.
