GEM

Gameboy Emulator (2015)

Features:

Includes debugger to disassemble and step through assembly instructions and a memory inspector.
Supports basic TAS (Tool-Assisted-Speedrun) input playback, but generally desyncs after a few minutes.

Future work:

Since 0xCB extension opcodes are uncommon, they have only been implemented on a per need basis.
Proper bank switching.

Demo
