Also, I'm not sure on all of the debugging commands, eg switch suit, switch room, blah etc, but you do need to have the "good_times" key in your registry
To enable debug mode then, click Start, Run, and type "regedit". Browse to:
"HKEY_LOCAL_MACHINE\SOFTWARE\LucasArts Entertainment Company LLC\Grim Fandango\v1.0". Right click, select "New -> String Value" and enter "good_times" as its name. Now double click this and enter "TRUE" as it's Value.
You'll have to figure out the rest yourself, or wait for someone smarter to drop by.
Then I wonder: What's the point of the debugger program for Grim Fandango. These instructions stand there too in the readme!
I found the link in the game debugger topic that was posted a while ago. Here:
