>>> IMPORTANT! <<< In order for the sound to work, the sound files must be located in the root directory of the system (boot) disk. Otherwise, the game will run but will be unable to find the seven sound files. (See Below) PMX Note! This arc has been updated: 1.this file did not work with Exp. ram: I ran it thru DJ James prg to fix this. 2. I couldn't get it to load sounds, found out there was a .sound file missing so I added one. 3. added b4arc and Afterarc to rename files If these are wrong blame me not the author.

Included are executable and documentation files, not to be altered without my consent. Program is called "Missile" and can be invoked from either CLI or the Workbench on 1.1 of any Amiga. If sound effects are desired, be sure the following files are present in the same directory as "Missile": 1. boom.sound 2. explosion.sound 3. alarm.sound 4. ready.sound 5. chime.sound 6. siren.sound 7. tick.sound You are free to change the sounds! These sounds were simply taken from the public domain, and new ones can be generated using a digitizer. However, be aware that if your new sound is not long enough, it will repeat over and over again. (I did this because if the sound terminated before the ADCMD_FREE was called, the system would sometimes hang when BeginIO/CMD_WRITE was later used for another sound. Why does this sometimes happen???) INTERESTING TIDBITS: * This is a multitasking program, so try running it 2 or 3 games at once! Of course, you'll probably want to freeze one while another is progress. * The sprites are not moved with the standard ROMKernel routines (this is the only impolite thing my program does), and for good reason: speed. Therefore, they do not follow the screen they're in, and they make a humorous distraction when you move the game screen to back! * For a slower paced game, run another program in the background. A good choice is a music program. Then the game has background music! * Source code is available from me and can be obtained with a kind donation of $5 to the following humanoid: Glen Merriman 5602 Oak Trail Houston, Tx. 77091 (You will get it on a disk from me if you send for it through the mail. Of course, the costs of the postage and the disk itself dictate that I charge an additional $3 for mail service). I have gleaned vast knowledge with this little project, and I will share it along with my other projects, including my machine language monitor/ disassembler which I used to debug my game, if you will be so kind as to help support my efforts.
