Cosmic-Conquest

Rick Carlino lead the effort to bring this game to GForth https://github.com/RickCarlino/Cosmic-Conquest-1982.

I enhanced the game for my own 16 bit cell Forth. It has the following enhancements:

  • Reformatted output to a 80 column by 23 line display with added game information on the left and an enlarged galaxy scan on the right,
  • Added a spiral galaxy scan to enhanced real-time play, allowing moves while the scan is in progress,
  • Added a "long-range" spiral galaxy scan showing an incomplete view of objects farther away (the dots in the image above),
  • Input is no longer case sensitive,
  • X or x now quits the game, and,
  • Eliminated non-standard words.

bfox9900 has a version with more refined Forth code https://github.com/bfox9900/CAMEL99-V2/tree/master/CosmicConquest.

  • cc_e.f enhanced version of original game
  • dforth.bin Forth and Cosmic Conquest binary for 65C02

How to play on a 6502 Emulator

  1. Install py65.
  2. Run py65 monitor, loading the 65C02 binary with py65mon -m 65c02 -r dforth.bin -i 880a -o 8400.
  3. The Cosmic Conquest Forth source code is located at $4000. The word LOAD will compile this code. This will take about 30 seconds.
  4. Run Cosmic Conquest with CONQUEST.

How to play on other systems

My enhanced version of Cosmic Conquest uses standard Forth-2012 words. It assumes a 16-bit cell. It should run on other standard Forths provided they accomodate a 16-bit cell. With other Forths you might need to make minor modifications where FLEETS and F use ! and @ to get my version running on a Forth with larger cells.
