New version of Scummbler (v2 r15). Changes:

• Fix "drawObject" in V3-4 (was missing 3rd argument and outputting the wrong opcode).
• Fix "getState" instruction's syntax (was originally defined as "if (getState(Local[0] == 0))", should have been "if (getState(Local[0]) == 0)").
• "debug?" instruction renamed to "debug".
• "PutCodeInString" - add support for a missing 2nd argument (as output by descumm).
• Restructure code path structure, separate out some tests.
• Added some tests based on my attempt to parse MI1 global scripts.
• Change license to MIT license.
• Update build scripts.
• Update to the manual - change info for "getState", add support e-mail to contact list.

I've discovered there are some bugs in descumm's output (introduced by yours truly). I discovered these after trying to parse all the global scripts from Monkey Island 1 VGA floppy.

Script 82 and 83 - missing 2nd argument for PutCodeInString

[0000] (27) PutCodeInString(24, );

When the string is empty, descumm outputs nothing for the second argument. It should output this:

[0000] (27) PutCodeInString(24, "");

Scummbler now supports either scenario.

 

Script 135 - unknown string function

Global script 135 contains this line:

[049C] (FA) VerbOps(Var[100],[SetXY(0,Var[228]),Text("How to deal with  frustration, disappointment, " + unknown8(8224) + " and irritating  cynicism."),On(),Key(Var[229]);]);

The "unknown8" instruction is incorrect, and can't be parsed by Scummbler. You must manually change the text like so:

[049C] (FA) VerbOps(Var[100],[SetXY(0,Var[228]),Text("How to deal with  frustration, disappointment,\xFE\x08  and irritating  cynicism."),On(),Key(Var[229]);]);

Also, there shouldn't be a semi-colon after the "Key()" instruction, but Scummbler handles this anyway.

 

Script 152 - not joining string functions

[00BF] (14) print(255,[Color(Local[8]),Center(),Text(getString(VAR_HEAPSPACE)keepText())]);

This line should read:

[00BF] (14) print(255,[Color(Local[8]),Center(),Text(getString(VAR_HEAPSPACE) + keepText())]);

Again, you'll have to manually alter the script.
