21C - New Open Source BlackJack/21 Game For Mac OS 8+ & more

[alexfree]

This is the first game I've ever written. Since I wrote it in C89 I got it portable enough to compile with Macintosh Programmer's Workshop. Let me know if you encounter bugs/fun with this!

You might interested in this Ansi C game lib and games:
https://github.com/Fabrizio-Caruso/CROSS-LIB/blob/master/docs/SYSTEMS.md
It still missing versions for Mac OS 9 so get contacted that developer.

Well done on creating your first game Alex.
But I lost money - reckon the dealer was cheating.

@teroyk My universal library and retro-hardware abstraction layer CrossLib is primarily meant for 8-bit systems but it also has some initial and minimal support for 16/32 systems. You can compile games written with CrossLib for some generic Linux ELF Motorola 68020 targets as well as some 68000/8 targets such as the Amiga, Atari ST and Sinclair QL. This is just an initial support and the current result is just a version of the game that runs on the console and uses ASCII characters for graphics.
I will eventually try to add real graphics on some of these systems but it does not have the highest priority.
CrossLib is meant for games with simple sounds and simple tile-based graphics (smooth animations are possible through pre-shifted tiles). This makes sense on 8-bit computers and less less on powerful 16/32 bit targets.

I’m glad you like it!
