  • Startrek with option to save/load game

    From ladislau szilagyi@21:1/5 to All on Thu Jun 29 12:19:31 2023
    Hi,

    Thanks to Alan Cox ( https://github.com/EtchedPixels/FUZIX/tree/master/Applications/games ), I had a very solid starting point...

    I made some adjustments for HiTech C, and added save/load game.

    You may find my Startrek here: https://github.com/Laci1953/RC2014-CPM/tree/main/startrek

    Do not forget to copy the st.fat, st.int, st.log, st.txt files on the disk containing the startrek.com

    I ported the game also on Bill Shen's Z80ALL.

    As an interesting detail, on Z80ALL the random number generator computes its "seed" value by summing all the screen's characters!

    Hi,

    I just received the following message:

    "Ensign Chekov : I have detected and fixed a malfunction in the phaser control computer"

    You may find the fixed StarTrek at https://github.com/Laci1953/RC2014-CPM/tree/main/startrek

    Thanks for the update. Btw. - may be you can explain why you implemented
    the save functionality as assembler, despite of the fact, that the game
    itself is written in C ...

    Hi Peter,

    I already had the save/load routine written in assembler... it is used also for backgammon, sargon78, sudoku.

    I just published a new version (better random number generator) for VT100.

    File rand.as was updated.

    Hi,

    I published also a new version for Z80ALL.

    Just to show how fast Z80ALL works, here is a listing of the Startrek building procedure:

    (clock is a small program used to measure time intervals, using the real time clock)

    It took under 3 minutes...

    The same procedure, executed on a RC2014 (CPU board SC108), takes more than 10 minutes...
