Porting game Stop the Express to BK-0010, work in progress.
The game for ZX Spectrum was written by Hudson Soft and published back in 1983. In 1990 the game was ported to Elektronika MS-0515 (PDP11-like computer based on T11 clone) by unknown programmer in Lwow (Ukraine). In 2017 I ported the game to UKNC. And finally in September 2018 I started porting this game to BK-0010 machine.
The real challenge was to fit 32K game into 16K RAM available on BK-0010. So I had to strip down the game: demo mode sequence removed, reduced number of tiles and re-worked the way the tiles drawn, removed locomotion tiles used on the last scene of the game, the info screen shown once at the beginning only and the memory reused after that, and finally I removed all sound effects.
