Galaxy Trek Adventure #1

Galaxy Adventure #1
I have already ported Howard Batie's second Star Trek themed text adventures for the Coco to the MC-10. The Coco program for his first adventure, which can be found in Hot Coco Magazine August 1983, was based on an original game for the TRS-80 16K by Randy Hawkins in 80 Micro (August 1982, pp. 174-184). In fact, the version I ported might be more akin to Mr. Hawkins' original, as I based it on some source code that I found for the TRS-80 Model 100, which might have come from the Model I version rather than the Coco version.  However, the fact that Batie's name is on it leads me to believe that it must be from the Coco version. I have source for the Hot Coco magazine version, but it's from OCR text of a scan of the article, and it was getting very tedious trying to get it into running form, so I switched to the source for the TRS-80 Model 100. I might still plunk away at the original magazine source, because Mr. Batie suggests in the article that there are some differences between his version and the TRS-80 Model I version, which might be nice to uncover. Also, the magazine version uses the technique of encoding all of the messages, so you can't cheat by looking at the source code.

There were a number of errors in the Model 100 source. Some of these problems are outlined in a Gaming After 40 blog post. I found others and corrected them. There was a big problem with how the game handled the button pushing for the impulse engines, that essentially allowed you to correct the orbit without having to solve the puzzle. GamingAfter40 suggests that the way to get rid of the Klingon guarding the Tribble on level 2 is to get the phaser, but really it was because he pushed the button for the engines on level 1 and triggered the bug (which moves the guards to the planet). The real way to get rid of the guards is to shoot all of them with the phaser. The phaser only self-destructs on the planet after you've done all the necessary shooting on the ship. There were also problems with beaming routines, that allowed you to beam down without Spock being present, but which indicate that he is present by the messages displayed. There were also some problems with how the score was accumulated.

I have bug tested the program pretty extensively and played it to completion a number of times. Here's a play-through for those who may have been frustrated by the game in their youth.

I also completed the clean up of two simple programs taken from OCR text of scans from Color Computer Magazine and Hot Coco Magazine. The first is a simple game called SPRINKS the second is a Mother's Day graphic and simple music demo called MOTHER:
