I have managed to convert the game: The Unforgivable Innocent, developed in pure Sinclair BASIC, to other development tools. Firstly the easy one was compiling using MCoder III which required the unchanged Sinclair BASIC program to be compiled. And then the conversion from Sinclair BASIC to Boriel Basic which implied several source code changes to make it work.

Finally I managed to release a brand new game: The Unforgivable Innocent, developed in pure Sinclair BASIC and obviously to be played on Sinclair ZX Spectrum computers.

This is a list of some humble collaborations in other projects:
