Options file

An options file stores Worms 2 scheme options. Unlike other games, this file does not also contain weapons options; those are stored in a separate file.

As in traditional Worms 2 fashion, most of the values which could be stored within one byte are stored within four. All types are little-endian. How many of these are actually read has not been tested. Options that are more commonly known by the community under different names are listed, with the actual Worms 2 names listed in bracketed quotes.

Offset	Size	Type	Description
00	7	char[7]	Magic number used to identify the options file. The string "OPTFILE".
07	4	sint32	Round time, measured in minutes.
0B	4	sint32	Turn time, measured in seconds.
0F	4	sint32	Ground ("Worm") retreat time, measured in seconds.
13	4	sint32	Rope retreat time, measured in seconds.
17	4	sint32	Mine count, measured in mines.
1B	4	sint32	Mine fuse ("delay"), measured in seconds (or -1 for random).
1F	4	sint32	Nonzero if dud mines might exist.
23	4	sint32	Maximum wind strength, measured in percent.
27	4	sint32	Friction. 0 = default, 1-5 = low to high.
2B	4	sint32	Number of kills required for an action replay to trigger.
2F	4	sint32	Amount of damage required for an action replay to trigger.
33	4	sint32	Nonzero if automatic action replays are enabled.
37	4	sint32	Maximum fall damage, measured in health points.
3B	4	sint32	Repeat swings of the ninja rope, measured in swings.
3F	4	sint32	Nonzero if round time is displayed ingame.
43	4	sint32	Land sink rate in sudden death, measured in pixels per turn.
47	4	sint32	Nonzero if worm energy is reduced to 1 at sudden death ("Energy reduction").
4B	4	sint32	Nonzero if an indestructible border exists around the map.
4F	4	sint32	Nonzero if girder radius is restricted ("Girder restriction").
53	4	sint32	Worm selection method. Zero if worms move in sequence ("No choice"), 1 for random (?) worm selection ("CPU decides"), 2 for worm selection ("Player decides").
57	4	sint32	Nonzero if extended cursor controls are allowed in the chat box ("Extended chat box editing"). No idea why this is in scheme options but it is...
5B	4	sint32	Hotseat time ("Delay between turns"), measured in seconds.
5F	4	sint32	Nonzero if stockpiling enabled.
63	4	sint32	Crate probability, measured in percent.
67	4	sint32	Crate intelligence, measured in percent (intelligent crates are biased to drop closer to losing teams).
6B	4	sint32	Health crate energy, measured in health points.
6F	4	sint32	Nonzero if crates can be booby trapped.
73	4	sint32	Nonzero if superweapons ("secret weapons") can appear in crates.
