Before you read, keep in mind the following things:
This FAQ will explain the several debug modes found in Sierra On-Line adventure games.


- References to "ego" mean "the main character" or the object you control.
Before you read, keep in mind the following things:
* References to "ego" mean "the main character" or the object you control.
* Any brackets, asterisks or quotation marks should NOT be typed in. They're only used to clarify.
* Anything between brackets means it's either a key or a combination of keys. So [CTRL + D] means you push the CONTROL-key and the D-key '''at the same time'''.
* Between quotation marks means it should be typed in.
* Words between asterisks should be replaced with a proper word/object/thing. So "PITCH *object name*" means you should type the object you want to get, e.g. "PITCH WIG".
And while you might know, Sierra games use an "interpreter". This basically is a
program/system which translates the program statements (in byte-code) into
executable machine code one line at a time as the program is running; as opposed
to a compiler, which translates the entire program before the program is executed.
The different interpreters used by Sierra for their games are described in the next chapter.

is a program/system which translates the program statements (in byte-code)

located directly in the game code itself, not in the interpreter's (although
the interpreter of course offers the commands to use in the script). So if a
game does not have the debug script in it's code, it will not work. However,
pretty much all the games have a debug mode, except for Mixed-Up Mother Goose
and the Manhunter series. The latter does have some unused messages relating
a debug mode in it, but it's likely removed from the final release. The demo
packs and other demonstrations also don't include a debug mode.

There are four major versions of AGI. AGIv0, AGIv1, AGIv2 and surprisingly,

AGIv3.

AGI (Adventure Game Interpreter)
AGIv0/AGIv1 are old and uncommon interpreters with no known debug mode. The
only games using them are the self-booting first versions of King's Quest 1 &
2 and The Black Cauldron, which are rare and hardly used nowadays. Donald
Duck's Playground uses a hybrid between AGIv1 and AGIv2, it does include a
debug mode.

AGIv2 and AGIv3 are pretty alike and so are their debug functions. Debug-wise

the only major difference is that AGIv3 does not contain the trace-function.

This debug mode is solely script related, which means that a debug script is
located directly in the game code itself, not in the interpreter's (although
the interpreter of course offers the commands to use in the script). So if a
game does not have the debug script in it's code, it will not work. However,
