Documentation for Planet Protector! Original Author: Mike Berro [75765,374] NEC Conversion: Gary Weber [gary@web8201.com] The Web 8201 Project: http://www.web8201.net ============================================= You are hovering above your home base on the planet NEC. Aliens have landed on your planet! Eight of their bases have been established. You must seek them out and destroy them, but each one is protected by a tiny heat-seeking missile. After you destroy all eight, they are re-built, and faster missiles protect them. However, they only have enough supplies to re- build four times. If you destroy all five sets of bases, you are proclaimed the hero of NEC! ==================== Download PLANET.DO, then load it from Basic. Run it, and it will create the file PLANET.CO. (It takes about three minutes.) Delete PLANET.DO as it is no longer needed. Run PLANET.CO. PLANET.CO is 2674 bytes long. It is located at 56000 to 58673. >>> BACKUP ALL YOUR FILES BEFORE USING THIS PROGRAM <<<. After you load the game, it should be safe to re-load your Basic and Text files. (I hate cold starts!) *** NOTE: You must also an implementation of the M100 graphics characters. This can be provided by the SARDOS 1.73 option ROM, or by CHR100.CO. ==================== When you run the game, the title page will appear. Press any key to continue. Your ship appears in the upper-center of the screen, above the words "Press the SPACEBAR to begin". Your difficulty level is in the lower- right hand corner of the screen. The vertical line next to it is your fuel gauge. The refueling base is on the surface of the planet right below your ship. There are no alien bases in sight. To move your ship, use the up, left, right, and down arrow keys. Pressing one of these four keys activates a thrust rocket to propel you in the approriate direction. Use reverse thrust to brake. You can go as high as you like, but there are no aliens up there. The planet is round, so you can go left or right until you return to your starting point. The force of gravity on your planet is weak, but those wily aliens have found a way to increase it as you destroy more of their bases (nasty little suckers!) To dock with the refueling base, you must slowly descend between the guide-rails until a beep sounds. You are then refueled. Don't linger, or the fuel will explode! You have a laser on your ship, but it only fires downward. You must be immediately above your target to destroy it. You do not get any points for getting the little homing missiles, but once you destroy one, it will not return until the next level. Hints: Practice docking with the base at the beginning when you are already over the base. Also, you may want to kill the little homing varmint near the base right away, so it won't bother you if you have to refuel. ==================== This program was assembled using Custom Software's excellent assembler program. The speed of this program and the ease of it's use allowed me to write this game from scratch in less than a week. Please let me know what you think of this game. I am always interested in changing and (hopefully) improving my programs. If you have any ideas for a game or utility let me know. All my Model 100 programs are available through the SIG. Mike Berro [75765,374] BCS Software ============================================================================== ============================================================================== *** IMPORTANT NOTE REGARDING CHR100.CO! *** If you are using the SARDOS 1.73 option ROM, you can ignore the following information as your M100 graphics characters will be conveniently loaded from the ROM automatically. If you don't have the SARDOS 1.73 and are instead using CHR100.CO, it will be loaded by PLANET.BA directly. (There is no need to engage the CHRLDR.BA proram to load CHR100 graphics characters.) *** INFO ABOUT THIS M100 to NEC CONVERSION *** This program is a Model 100 conversion of Mike Berro's PLANET.CO. The software used to convert this machine language game is called "BINCON" and employs the use of my RAM/ROM address cross reference table. If you encounter any lockups or odd behavior, please let me know. You can contact me through the Web 8201 web site, at http://www.web8201.net. ============================================================================== *** GAME COMPLETION: GET A PRIZE!! Still unclaimed May 27, 2021 *** ============================================================================== If you succesfully destroy all the alien bases, the game ends and something rather peculiar happens. The first person to tell me what happens (as proof that you completed the game!) will get your own customized option ROM created and shipped to you with your chosen collection of programs for the NEC free of charge! Or, you will be provided a REX option ROM binary image if that is your preference. See the Web 8201 web site (http://www.web8201.net) and view the Custom Option ROMS page for details. I will post the contest winner on the Web 8201 front page. As of May 27 2021, the prize has yet to be claimed!
