Grime 68000 - porting a z80
game for 5 different 68000 Systems in 7 Days!
68000... on (almost) every 68000 system you could imagine!
|Grime is an old DOS game I used to
have on my PC XT... it was a simple little text game, that was a lot
Grime was written by Mark Elendt... as far as I remember I got it
from an old magazine coverdisk...
currently Grime is 'abandonware'... no one seems to really remember
it, and it's trickyto get working on a modern pc, as it runs too
fast!!.. you can get the orignal here
At the start of July 2018, I started a 7 day programming project to
recreate 'Grime' as a Z80 based game... I chose it because it's fun
and simple, and this gave me a good opportinity... I wasn't just
going to remake Grime... I was going to make it work on 11 different
I remade grime as 'Grime Z80' which uses one piece of logic
code that plays on 11 different Z80 systems... namely: Amstrad CPC,
ZX Spectrum,MSX1, MSX2, Enterprise, Sam Coupe, TI-83 calculator,
Gameboy, Gameboy Color, Sega Mastersystem and Sega Gamegear!
But why stop there... I now had a simple game 'template' which could
be extended for something new... why just limit it to the Z80? so in
December 2018 I started the project again... this time as Grime

Grime 68000 was a quick programming experiment, not a commercial
quality game, it has NOT been tested on real hadware, and may not
It was produced as an educational challenge during my week off, and
I do not intend to spend any more time on it... if it does not work
on your hardware, you can concider it 'homework' to fix the bugs!
