Johan Koelman


After SAM2_ZX81 Johan is working on a new emulator, named SAM2_GB.

This is a Nintendo Gameboy emulator running on a standard SAM Coupe, without i.e. a Mayhem Accelerator.

The progress can be followed at

In July 2007, Adrian Brown started to help Johan out with the coding, and has proceeded to update the CPU core and rewritten the graphics routines.

Latest progress diary and screenshots appeared in issue 19 of Sam Revival magazine (Sept 2007)
