Ender from the ScummVM team and some other people recently discovered some debug modes in Monkey Island 1, Maniac Mansion & Zak McKracken.
Check out this link to learn more about those debug modes:

Hmm, I did know about debug modes in MI1 and MM, but not in Zak McKracken... And now I have a total list of key combinations, I previously knew only few of them...

Well, I knew a bug or something other in Loom, the diskette version. I'm not sure what you'd call it. When you pressed "m" on the keyboard, you could flip through the ego's sprites for different distances on the background. For example, if you saw Bobbin in the foreground as seen in the tents at the beginning of the game, you would press "m" once and he'd look like he was walking in the hall with the tapestries on loom island or in most of the places inside the glassmakers palace.

Eero: Where did you learn about the debug modes in MM & MI ? I tried to search for it in google, but found nothing.

SGreenslade: I tried your "bug" but couldn't recreate it. is it possible you were using using a rare version of loom? mine is the standard ega diskette version, with SCUMM version of 3.5.40 .

Does the ega version have midi support? I'm not sure what version I have. It's in 3.5 floppies though. I think it's in vga. My manual says I can go back to ega or cga using commands after the executable. It may be the letter "p" or "l"...I don't remember, sorry.

I found them myself when digging in SCUMM... Also there is certain debug mode in MI2, DOTT and CMI, but I couldn't access those (or just don't know how they work)... :-\

Hmm, I didn't know anything about Loom... Have to try it...

well - I have 3 versions of Loom:
Loom EGA - SCUMM Ver. 3.5.40
Loom EGA Hebrew - SCUMM Ver. 3.5.40
Loom CD VGA - SCUMM Ver. 5.1.42

I also have the Loom Demo - ver. 3.5.20

Can you tell me what versions do you have?

Omer.

Interesting topic...

There was a buggy version around of Loom, which used, instead of the usual "LFL" extension (as in 001.LFL), an "NYC" extension... NYC were the initials for some cracker group, IIRC... But that's probably not the version mentioned, since it seems to be an official release (the manual part gave that away)...

Well, I dug up this old post, and thought that I should include the fact that I don't own (at least those) versions anymore.

SGreenslade, could you send me your version... I personally am very interested of bugs like this...

The version number? Or the whole game? I'd have to install it to confirm the version number though. Not to mention it would be a good opportunity to find the bug again or whatever the heck it's supposed to be.

Now that's insanity. Anyways, I suggest you have me upload it somewhere. If that's not possible, there's always AIM or Yahoo Instant Messenger, but that would be harder since we have conflicting schedules here.
