All these cheats assume you're running atari800 built with debugger
support. To get into the debugger, load the game normally, then press
F8. After making changes in the debugger, give the "cont" command to
get back to the game.

If you're using some other emulator besides atari800, see its
documentation for how to enter/exit its debugger, and how to change
memory (the "c" command in atari800). Specifically, don't ask me,
'cause I don't know :)

Infinite Lives
--------------
Well, 200 lives, anyway. Start the game, wait until the intro music
is done and Jumpman has finished materializing, then press F8. In the
debugger:

c 70a c8
cont

The game will still display 3 lives, until you get killed the first
time. Then it'll display a bunch of lives with a + next to them.

The "c8" can actually be up to "ff" (255), but if you ever get over 255
lives (due to getting extra lives), it'll overflow to zero and the game
will be over the next time you get killed!

If you start running low on lives, you can use this cheat again.

Warp to Level
-------------
To start the game on a particular level, press F8 at the "Player #1
Speed?" prompt. In the debugger:

c 6f6 3
cont

The number you enter is the level number minus two. In the example, the
game starts on level 5 (Figurits Revenge). Remember the monitor uses hex,
so use "a" for 10 (which will start on level 12). For level 1 you'd use
"ff" (aka -1 in twos-complement). Entering "b" (for the nonexistant
level 13) will take you back to the "Number of Players?" prompt. Any
other invalid level will make the game lock up when it starts.

This cheat also works during a level, but it won't take effect until
you finish the level you're currently playing.

Random Levels
-------------
This is like the randomizer mode in the original Jumpman. At the "Number
of Players?" or "Player #1 Speed?" prompt, press F8, then:

c 6f3 1
cont

This cheat also works during a level, but it won't take effect until
you finish the level you're currently playing.
