ACS Mini for the Sharp MZ-80A (Entry to the PUR-80 category).

Description
-----------

ACS Mini is a version of the often cloned Blitz-game. I originally created a game called Alien City Sharp, inspired by Alien City Blitz on the Commodore 64, while learning to program BASIC SA-5510. ACS Mini is an attempt at turning this game into a tenliner. Some sacrifices had to be made, but it mostly works just like the original version. 

The game is for the Sharp MZ-80A computer / BASIC SA-5510.

Instructions
------------

Instructions are found in line 3 of the program listing. Here's the extended version:

You're piloting an UFO that has unfortunately run out of space-diesel. Now you need to clear a landing area, by flattening the nearest city using Building Obliterating Monster Balls. You can only have one B.O.M.B. in the air at any given time. If you hit a skyscraper, it is game over and the game will restart.

If you have destroyed all the buildings, you may activate a landing check which will enable you to move to the next level if the ground is cleared. You will even get a nice fanfare, as a reward for completing your mission ahead of landing time. Then, unfortunately, the disaster will happen all over again, only the next city will have more and potentially taller buildings. Oh, well!

There are two keys to use:

5 - drops a bomb from your UFO. It will be dropped from the center spot of the UFO.

8 - checks if the ground has been cleared. You can use this after bombing the entire city, to skip the manual landing. Saves a lot of time!

Compatibility notes: While I have not tested the game on other models of Sharp, eg. the MZ-700, I do not think it is compatible as it uses the 2KB of screen RAM on the MZ-80A to work.

Start Via Emulator
------------------

01. Download the Common Source Code Project from :
    http://takeda-toshiya.my.coocan.jp/common/index.html
      (look for the "Binary Archive" link beneath the list of emulated systems)

02. Unzip the downloaded ZIP file which will give you a folder called "Binary"

03. Inside this folder there is a 2nd folder called "Binary", underneath this
    you will find mz80a.exe in yet another folder called "Binary" Please make
    sure to copy all ROM files which I have placed into the Jetpackman.zip
    file into the same folder where you find mz80a.exe.

04. Double click mz80a.exe which will begin the emulator. Go to the Device
     menu and click Sound. Turn off all the sounds otherwise you will hear all
     the tape loading noises.

05. If the screen is very small, use the "Host" menu to change the screen size
    to something you prefer.

06. At the "Monitor SA-1510" screen type the command L and press Return / Enter.

07. Choose the CMT menu and click Play.

08. Browse to the MZF file containing BASIC (BASIC.SA-5510.MZF) and double click.

09. BASIC should now be present in memory. Go to the CMT menu and click Eject.

10. Within BASIC type LOAD and press Return / Enter.

11. Again go to the CMT menu, click Play and browse to ACS Mini v2.mzf and
     double-click it. You might have to manually activate the play button (in 
     the CMT menu).

12. Once the game has loaded just type RUN and press Return / Enter to play
     the game or you can type LIST to list the program.

Note: You may also use drag & drop to place mzf-files into the virtual cassette deck.
