#8445 closed patch

Two small fix for descumm

Reported by: SF/albeu Owned by: fingolfin
Priority: normal Component: Tools
Version: Keywords:
Cc: Game:


First allow descumming v6 script with a size of 9. These are pretty common in dott: 8 bytes for the header plus one byte for the return op. Not so important but when one descumm a whole game it's nice to have all scripts, even if they are "empty".

Then fix the systemOps opcode, this one is wrong since long.

I also have some code to decode imuse commands and i could add a couple engine variable names (the GUI stuff). If you are intersted i'll submit that later.

Thanks, commited to CVS.

As for the engine variables: Depends on what exactly you mean. In general, we only add those vars to descumm which are used in ScummVM, i.e. those vars which have a meaning to the engine. We could of course compile tables for the other variables, too, but they are usually game specific, and even differ to a degree between different versions of a single game, so we tend not to bother.

Alas, I do not know what you have in mind precisely, so take this comment with a grain of salt!

I do mean variables used as interface to the engine (v6 only as useal with me). These are minor but imho it can be nice to have them.

Currently I found a bunch of variable that hold the strings used for menus, an array that have the colors for the menus, the debug password and a variable to set the game version (the engine then refuse to load saves with a mismatching version).

I tested them all with the original interpreter (v 6.4.3 Jul 10 1995 14:39:19) so i'm pretty sure they work. My test game also partially work with the samnmax interpreter (7.0.2 Jun 09 1994 13:52:31) and it show that at least the menu variables are the same.

I'll submit that as soon as i can update my cvs, so probably tomorrow :(
