Descumm tool

Post by johncl »

Hi, I am trying to get Monkey Island EGA version into a more readable human format after going blind from looking at bytes in the files. :)

So I tried the DESCUMM tool that is part of the tool package. But when I try parameter -4 (which is the version for Monkey Island I only get back an "ERROR: Unknown script type!" message. :(

I also tried -1 and -2 which seems to start some script output but after a few lines stop with "unknown subop nnn". Btw I am using the lec files as input here. Perhaps that is wrong?

It's not meant to be run on the game data files. Rather, you have to tell ScummVM to dump scripts as they are loaded by the game (with the -u or --dump-scripts command-line option). So it's more useful for debugging strange game behaviour than for studying an entire game.

I don't know if there are any tools available for dumping every script in the game, or anything like that.

Hm, but descumm.exe is a separate command line tool part of the toolkit download? The -u option is for the scummvm directly from what I can read in your answer? I tried that now but it doesnt seem to work.

The -u option in ScummVM tells it that whenever it loads a script, it should also write it to a file, and those files are what descumm handles. (There may be other ways, but that's what I've been using occasionally.)
