Adventure was written by Warren Robinett and is copyright 1980 ATARI, INC, and is a classic and well-deserved hit.

In 2002 Joel Park and others decompiled and commented the Adventure code. (http://www.qotile.net/minidig/) and (http://www.biglist.com/lists/stella/archives/200206/msg00094.html)

In 2006 Peter Hirshberg created a C program that mimics the assembly with very high fidelity. (http://peterhirschberg.com/adventure/index.htm)

In 2011 Michael Kohne ported Peter's code to Java and built it for the Android platform (right here).

This program is the result. I had to port Peter's code to Java, and I had to build enough of an Android app to make it go. I simulated the Atari console controls with custom buttons, and the joystick and fire button are on-screen.

Why have I ported Adventure to Android? The same reason so many people write Pac-Man clones - I needed something to use as an initial learning project for getting familiar with the platform. Adventure is perfect for this purpose, as I pretty much KNOW how it should work, so I don't have to design a game, and it's complicated enough that I learn a good amount about the platform. 

The code attached to this web page is bound to have bugs, and frankly the joystick control could look a bit nicer. It uses API rev 7, so it should run on most devices, though I didn't do medium and low res graphics for the buttons, so I don't know how well those will work.

The Joystick widget is from http://www.java2s.com/Open-Source/Android/Widget/mobile-anarchy-widgets/com.MobileAnarchy.Android.Widgets.Joystick.htm

If you notice any bugs, please contact ME, not anyone else, because they are probably due to my port, not anyone else's mistakes.
