CoCoFun

Random CoCo 3 code written with CMOC. This repository is intended to be a fun way to write quick and dirty little programs for the CoCo 3 and also revisit old Assembly and Basic programs that I wrote in the late 80s and early 90s before I had any formal software development training. More recently, I used it to enhance CMOC's optimizer.

There are several folders which are described below.

• Ancient - Very old (from the 80s) assembly language programs
• Balloon - You are a ballon on a skateboard that must avoid a pin. This was my first real assembly language game and was written around 1988. This game did not use CoCo 3 graphic modes because I did not know how to access them. After writing this game I decided to work on something that actually used CoCo 3 graphic modes and did not need double buffering.
• Bouncy - Use C code posted by Lee Patterson to enhance CMOC compiler optimizer.
• Card - A small CoCo 3 Christmas Card program that blends a scenic winter view with Christmas music
• cfgs - Configuration directories for testing programs with mess
• Demo - A cheesy little demo program to test CMOC
• Misc - Folder containing scripts to help import graphic data
• Primes - Use CMOC to calculate prime numbers.
• Rick - You are Rick Tracy and ... I never finished this game. The intent was to take advantage of CoCo 3 graphic modes, implement real sprites and double buffering.
• Splinter - A Breakout clone written in C and assembly language. This was originally written around 1989 in pure assembly language. The purpose was to learn how to use the CoCo 3 graphic modes and to write a game in such a way that does not require double buffering. The newer version adds slightly better graphics, background sounds and replaces joystick support with keyboard support. It still does not implement double buffering - this results in visual "tearing" that can be seen when the ball is in motion and artifacts when bitmaps are close to each other.
