Of all the AGI games, it is unknown whether the [[King's Quest IV: The Perils of Rosella AGI|KQ4AGI 256K version]], [[Manhunter: New York|Manhunter 1]], [[Manhunter 2: San Francisco|Manhunter 2]] and [[Mixed-Up Mother Goose]] have a debug mode or not. KQ4 will almost certainly have one, while Mixed Up Mother Goose probably doesn't even though its [[WORDS.TOK]] file has all the debug words contained in it. [[Manhunter 2: San Francisco|MH2]] has some kind of debug mode which allows you to teleport and change variable values because there are text messages in the first LOGIC file along these lines. [[Manhunter: New York|MH1]] probably has the same debug mode.

Again, the debug mode is usually activated by pressing ['''ALT + D''']. However, there are some alternative ways/exceptions with some games. These games require a certain sentence to be typed in; perhaps this was done to access the debug mode on other platforms, without redefining keys in the code. The games and their sentences are:

Partially based on the On-Line Debug Mode FAQ by HWM

 


Introduction

This debug mode is solely script related. A debug script is located directly in the game logic itself, not in the interpreter (although the interpreter of course offers the commands to use in the script). If a game does not have the debug script in its logic, 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 to a debug mode in it, but it's likely removed from the final release. The AGI demo packs and other demonstrations also don't include a debug mode.

AGI1 is an old and uncommon interpreter. The only games using it are the rare first (booter) versions of King's Quest 2 and The Black Cauldron. However, the AGI1 games do have a debug mode, so they're included here. Donald Duck's Playground is also a booter game, but in many aspects more like AGI2, including the version number given by Sierra (v2.001), so it's listed under AGI2. The first release of King's Quest 1 is sometimes listed as AGI0, but technically this more a container category for the first versions of the first release of King's Quest, not really one interpreter.

AGI2 and AGI3 have few differences and have similar debug functions. Debug-wise the only major difference is that AGI3 does not contain the trace-function. AGI3 games are Gold Rush!, King's Quest 4 AGI, the Manhunter series and a certain version (v2.10) of The Black Cauldron. Some demos also use AGI3. The rest of the games use AGI2.

 

Activating Debug Modes

Most AGI games still have the debug code that developers used while the games were being developed. Most of the games activate their debug modes by simply pressing the [ALT-D] key combination. The other games use a "magic phrase" to enter the debug mode. Once activated, here are commands that can be used.

 

Activating AGI1 Debug Modes

In King's Quest 2, the debug mode is activated by entering "FAST SPEAK" at the command line. It will be activated on room change. In The Black Cauldron, the debug mode is activated by pressing [ALT + D]. This would eventually become the standard way of activation. The debug mode will be deactivated on room change. Also, activating the debug mode multiple times will generate multiple input/output lines!

Game Debug Phrase
King's Quest II "fast speak" (activated on room change)
The Black Cauldron Alt+D

 

Activating AGI2/AGI3 Debug Modes

Of all the AGI games, it is unknown whether the KQ4AGI 256K version, Manhunter 1, Manhunter 2 and Mixed-Up Mother Goose have a debug mode or not. KQ4 will almost certainly have one, while Mixed Up Mother Goose probably doesn't even though its WORDS.TOK file has all the debug words contained in it. MH2 has some kind of debug mode which allows you to teleport and change variable values because there are text messages in the first Logic file along these lines. MH1 probably has the same debug mode.

Again, the debug mode is usually activated by pressing [ALT + D]. However, there are some alternative ways/exceptions with some games. These games require a certain sentence to be typed in; perhaps this was done to access the debug mode on other platforms, without redefining keys in the code. The games and their sentences are:

Game Debug Phrase
Gold Rush! "bird boy" or "bird man"
King's Quest 1 Alt+D
King's Quest II "fast speak" or Alt+D
King's Quest III "rats ass" (v2.14) or Alt+D
King's Quest IV AGI Alt+D
Leisure Suit Larry 1 Alt+D
Police Quest 1 "stink bug" or "stink bugs" (v2.0G)
Space Quest 1 "backstage" or "dbg"
Space Quest II "dbg" or Alt+D
