About the Emulator:

I wrote this emulator entirely in C++.  The version supplied here was compiled under Visual C++ but I also have a Borland C++ Builder version which has a lot more diagnostic screens that I used during development.  There are dump, CPU, and disassembly windows in that program.

The design is completely object-oriented; there are objects for all of the Atari chips, RAM, ROM, CPU, bus, etc.  I put great effort into writing code that could be well optimized by the compiler.

Miner or Bounty Bob never relied on any code from the Atari system ROM so it isn't included in this program,  It's a fairly complete Atari Emulation system and would probably run other games if I were to try.

There were a lot of details I had to take care of to make sure the output was as faithful to the original Atari 800 screen.  I used a great many of the Atari's features back then when I wrote these games.  And all of it came back to haunt me when I wrote this emulator because I had to replicate every Atari feature I used!  Even some of the copy protection stumped me for awhile.  Back in the 80's I was coding things cryptically to attempt to confuse anyone disassembling the program.  It's pretty funny that I turned out to be one of those people!

You can use alt-enter to switch to a full screen display mode, but this requires Microsoft's DirectX and an appropriate graphics card.  Visit Microsoft's web site if you don't have at least DirectX 7.

I don't promise that it will work on every PC known to mankind but I have tried it in Windows NT, 2000, 98, and ME and it works pretty good.  If you choose "max speed" on some fast machines you can really get cranking!

Use the menus to discover what keys map to the game input functions.  This version doesn't support any joysticks - yet.

Version History:

January 18, 2007:    Corrected an issue preventing the Bounty Bob secret "warp" codes from working properly.

Bounty Bob Strikes Back! - Cheat Code

Press F3 to enter the option screen.
Use the down arrow to move to the "Special Code" line.
Use left/right arrows to select 61800. Holding ESC will cause the numbers to advance more quickly.
Hold the "F" key on the keyboard and press F3.
Now when you're playing the game you can type any two numbers to jump directly to that level. For example type "05" for level five.  

After entering the cheat code as described above the following additional keys are active:

Restarts the same level


Allows Bounty Bob to be positioned anywhere on the screen using the arrow keys.  Bounty Bob is immune to alien death during this time although you can still claim treats.  Special equipment (such as a grain elevator) stops moving and acid rain stops falling.
