Some more documentation updates. Maybe we can recruit a webpage maintainer 

at some point, since this type of work bores me to tears :(

<body>
<p>Stella 2.0 contains support for Bob Colbert's Cheetah cheat codes, as
well as an extended Stella-specific type of cheat code that works on
bankswitched ROMs.</p>
<p>To enter a cheat code, press Ctrl-C during emulation to bring up
the Cheat dialog, and enter your code there. Press Enter when done,
or Escape to abort if you change your mind.</p>
<p>Cheetah codes are explained in detail on Bob Colbert's web page, along
with a list of codes for various games:</p>
<p><a href="http://members.cox.net/rcolbert/">http://members.cox.net/rcolbert/</a></p>
<p>Briefly:</p>
<pre>
6-digit (cheetah) code: aaaddc
aaa = address - $f000
dd = data
c = count - 1
</pre>
<p>Cheetah codes don't support bankswitched ROMs, so they only work for
2K or 4K ROMs.</p>
<p>Stella's extended cheats are similar to Cheetah codes, except that
they can be 7 or 8 digits long, with the extra digits used for the
bank number:</p>
<pre>
7-digit (stella) code: baaaddc
b = bank (0 to $f)
aaa = address - $f000
dd = data
c = count - 1
8-digit (stella) code: bbaaaddc
bb = bank (0 to $ff)
aaa = address - $f000
dd = data
c = count - 1
</pre>
<p>Here are a few cheat codes I've found:</p>
<pre>
Pitfall (standard Cheetah codes):
5b0ea1 - infinite lives
723ea1 - infinite time
aa5??0 - set starting level, ?? = 01 to ff (d0 is kinda neat)
Battlezone (Stella extended codes):
1236ea1 - infinite lives
Ms Pac-Man (Stella extended codes):
108fea1 - infinite lives
</pre>
<p>The next release of Stella (2.1 or 3.0) will contain a much nicer
user interface for managing cheat codes, along with a database
of cheats. If you've found any new cheats, please send them to me
(atari@hardcoders.org), so I can include them in the database. Ideally,
I'd like to collect at least infinite lives/time cheats for every
game listed in stella.pro.</p>
<p>Enjoy!</p>

<p><b>FIXME</b> Add snapshots and description for cheat manager. <p>Stella 2.0 contains support for Bob Colbert's Cheetah cheat codes, as
well as an extended Stella-specific type of cheat code that works on
bankswitched ROMs.</p>
<p>To add/remove/edit a cheat code, enter the 'Cheat Code' dialog:<br><br>
<img src="graphics/cheat.png">
<br><br><br> <p>Currently, there are three types of cheatcodes available, all of which
must be entered in hexidecimal format:
<ul>
<li><p>Per-frame RAM cheats:<br>
Evaluated each frame, and apply to RAM only. Format as follows:
<pre>
4-digit code: c041
c0 = address
41 = data
</pre>
</li>
<li>Cheetah codes, which are explained in detail on
<a href="http://members.cox.net/rcolbert/">Bob Colbert's web page</a>,
along with a list of codes for various games. Cheetah codes
don't support bankswitched ROMs, so they only work for 2K or 4K ROMs.
Format as follows:
<pre>
6-digit (cheetah) code: aaaddc
aaa = address - $f000
dd = data
c = count - 1

</li>
<li>Stella extended cheats are similar to Cheetah codes, except that
they can be 7 or 8 digits long, with the extra digits used for the
bank number:

7-digit (stella) code: baaaddc
b = bank (0 to $f)

8-digit (stella) code: bbaaaddc
bb = bank (0 to $ff)
aaa = address - $f000
dd = data
c = count - 1
</pre>
</li>
</ul>
<p>There's also the concept of <i>one shot</i> codes. These codes work
exactly the same as above, except they aren't saved. They are evaluated
once and immediately discarded.
<p>Here are a few cheat codes we've found:</p>
<pre>
Pitfall (standard Cheetah codes):
5b0ea1 - infinite lives
723ea1 - infinite time
aa5??0 - set starting level, ?? = 01 to ff (d0 is kinda neat)
Battlezone (Stella extended codes):
1236ea1 - infinite lives
Ms Pac-Man (Stella extended codes):
108fea1 - infinite lives
