Booty: Routine at 43764

This is similar to UnpackAllRooms, however instead of copying ALL the room data from the default room data into the rooms data buffer, this routine copies a single room from the room data buffers into the active room buffer. The reason for this is that the game opens with the default positions for everything held by the defaults but as the player moves around the game and interacts with doors/ keys/ items/ etc, the buffers keep track of what's been collected, and where the pirates were when the player left the room so when they're revisited, they can then retain those changes.

In TableRoomData the pointers to the room data are stored backwards from 22-1.
UnpackRoom	43764	LD A,(23508)	Take 22-*TempCurrentRoomID then multiply by 2 (as it's an address we fetch, so is 16 bit) finally add TableRoomData to point to the correct room buffer data address in the room data table for the current room and store the pointer in HL.
	43767	LD E,A
	43768	LD A,22
	43770	SUB E
	43771	LD E,A
	43772	SLA E
	43774	LD D,0
	43776	LD HL,47785
	43779	ADD HL,DE
	43780	LD E,(HL)	Fetch the room buffer data address for the requested room and store it in DE.
	43781	INC HL
	43782	LD D,(HL)
	43783	INC HL	Does nothing, HL is overwritten immediately below.
Move the room buffer data address pointer to the room data itself (the first 8 bytes are colour data). There's no need to copy the colours again, as they don't vary between each game.
	43784	LD HL,8	DE+=0008 (using the stack).
	43787	ADD HL,DE
	43788	PUSH HL
	43789	POP DE
Now move onto actually copying the room data.
	43790	LD HL,47831	HL=BufferCurrentRoomData.
Set up counters for copying data from the default state to the room buffer. The counter length relates to the length of the data for each instance of the "thing" being copied (NOT the length of the data being copied). For an example; portholes are 3 bytes of data each, so B is 3 when calling CopyRoomData. How many portholes being copied just depends on when the loop reads a termination character (255).
