     Download digitally archived Bally Arcade tape programs that will load with Bally BASIC (the BASIC without the built-in tape-interface).

     Paul says, "I found the handwritten source code to be easy to read, and only found one error in the two I checked through--Super Wumpus and Down The Trench. I haven't done anything with Hit The Pedestrian, Munch, Submarine Minefield, and UFO Battle, but I'd say these are certainly candidates for typing in."

Program Name Source Comments
Biorhythms & Moon Landing Tape 1980
Biorhythms & Moon Landing was a joint release by Cursor and Sebree's Computing. Along with the two programs, it includes a title screen for the tape. Moon Landing is probably the most sophisticated version of a Lunar Lander-style game I've seen for the system. After landing, you have to take off and dock with another ship, which is pretty tricky.
Down The Trench   1979
Down The Trench portrays an attack on the Death Star. If there's any strategy to avoiding the enemy lasers, the archiver didn't figure it out. But he did finally beat it on an easy difficulty. It's fairly intricate in that it has two stages to the game, plus an ending animation.

Star Fire   1980
"Star Fire is a cockpit-perspective space shooting game. I found it difficult to locate the enemy ships, however. I found this in both Bob Fabris' and Brett Bilbrey's tapes, but in slightly different versions. The one from Brett Bilbrey matches the code on-line, which is labeled as the "H.C. Version." I'm not sure what H.C. means. The one from Bob Fabris has a few lines different, and a comment in the code calls it the "JY VERSION." This version kept crashing on me. It seemed to archive OK, so since the tape doesn't look like a release version, maybe it's just an early prototype. The code on-line also has the Star Fire Assembler. This wasn't on the tapes, and I haven't typed it in."

Star Fire Assembler   1980
The STAR FIRE program uses a user-defined subroutine located in the BALLY's [8k] ROM, this assembler is a program which assembles (writes) a machine language program to store on tape for use in a BASIC program, which CALLs the machine language program from it's location in the Input Buffer. The user can define his own character, and use it any way he wants in the area of graphics. Because the program is in machine language, it runs many times faster and is MUCH easier to use then putting BOXes on the screen with BASIC.

Example shows bowling ball character table 9x9 size. [Graphic of bowling ball in binary table not shown]

Size of character is specified in lines 150 (Horiz) & 160 (Vert). Character table (at left) [not shown] is stored in lines 210 to 250. GOSUB C increments by 2, GOSUB D increments by 1. You can use table at left by using GOSUB D and input (X=Number), starting with (shown at left) X=28;GOSUBD;X=0;GOSUB D; X=127;GOSUB D;X=0;GOSUB D;X=127...etc. Remember to change the size parameters at 150, 160.

If you like what you see that you can do [in machine language, you can order my TUTORIAL on the use of the Internal Subroutines Character Generator. This will cover the complete use of this software, and show the user through examples, how he can CALL his own characters onto the screen and make them move around in REAL TIME, total Machine Language control.

XY Tutorial Tape 1979
This archive includes the six programs included with the "XY Tutorial." This tutorial demonstrates how to use the BASIC XY command, including achieving some rudimentary perspective.

Demonstration Program #2 on page 5 of the tutorial has a program, and then some additions to the program. The tape just had the program followed by the additions, but the program has been archived in two versions: both with and without the extra lines. The tape didn't include the short program on page 7, but it was typed-in and called Demonstration Program #4. Finally, there's a cool flight-simulation type program."

1) 3-D Forward Simulation Above A Flat Plane
2) Cartesian Coordinates To XY Values Routine
3) Demonstration Program #2
4) Demonstration Program #2 (with Additions)
5) Demonstration Program #4
6) RND XY Value To Perspective Point
