		const char *	fmap,
		const char *	path,
		W8 *	palette,
		W32 *	ceilingColour,
		char *	musicFileName[],
		parTimes_t *	parTimes,
		char *	format
	)

Convert map to Redux file format.

Parameters:

[in]	fmaphead	Map header file name.
[in]	fmap	Map file name.
[in]	path	Path to save redux map to.
[in]	palette	Pointer to palette array.
[in]	ceilingColour	Array of ceiling colours.
[in]	musicFileName	Array of music titles.
[in]	parTimes	Struct with the parTimes.
