cbmbasic is pretty cool. It’s a portable C rendition of the Commodore 64’s ROM BASIC interpreter. While not the spiffiest version of the language, it does allow some very old code to run â€” such as the games from David H. Ahl’s book BASIC Computer Games.
Here are all the programs automatically converted to cbmbasic’s tokenized format: cbmbasic-Ahl-BASIC_Games. They seem to run, but some might fail. Notes on sources of the text files and conversion methods are in the archive. Have fun!
