Thank you! I looked through the BASIC and it seems pretty straightforward, just a square-root function and a few places where it's using floating point. It is really hard to play. He tried to add some complexity by having the computer continuously run in the background and uses inkey$ to grab commands and they are not very responsive. Plus he makes you type the entire word instead of just using a single letter. I tried the SCHIRM command over and over again and it would never ping me for a value, so not sure why I couldn't raise shields. This goes into the Star Trek Last Battle column for me...that game was MC code and really nicely laid out but the game-play just made it too difficult to enjoy (i.e. screen jumping around, animations, etc...). I'll have to see if I can improve it if I can convert it to run on the ZXSimulator. The display layout is really nice, I like it.Chr$ wrote:Talking of Startrek clones on the ZX81, many years ago a chap called Kilian Schlaich made a version that was retailed by ISS in Germany. I found a copy in 2019 and was able to digitise it, then track down Mr Schlaich. He gave me permission to share it freely and because the cassette contained no instructions (I don't know if it ever did) he wrote some for me, 38 years later.
Here it as as a zipped .p file, with text file instructions (all in German).
Interesting how many Star Trek clones are out there. That's the 5th one for the ZX81...I found 2 on the QL.
