Adrian Smethurst – aka. cmonkey – is a cool guy and does a lot of stellar work modifying arcade games.
In October 2015 he recoded a ZX Spectrum game and released a port of Sokoban – called Sokoban L.E. for Taito’s L System arcade hardware.
The project and associated files were originaly posted on UKVAC. However, the site requires registration to access the homebrew section, so I’ve decided – with his permission – to host his files here, since he doesn’t have his own site.
