Booty: Routine at AAF4

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 16-01.
UnpackRoom	AAF4	LD A,($5BD4)	Take 16-*TempCurrentRoomID then multiply by 02 (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.
	AAF7	LD E,A
	AAF8	LD A,$16
	AAFA	SUB E
	AAFB	LD E,A
	AAFC	SLA E
	AAFE	LD D,$00
	AB00	LD HL,$BAA9
	AB03	ADD HL,DE
	AB04	LD E,(HL)	Fetch the room buffer data address for the requested room and store it in DE.
	AB05	INC HL
	AB06	LD D,(HL)
	AB07	INC HL	Does nothing, HL is overwritten immediately below.
Move the room buffer data address pointer to the room data itself (the first 08 bytes are colour data). There's no need to copy the colours again, as they don't vary between each game.
	AB08	LD HL,$0008	DE+=0008 (using the stack).
	AB0B	ADD HL,DE
	AB0C	PUSH HL
	AB0D	POP DE
Now move onto actually copying the room data.
	AB0E	LD HL,$BAD7	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 03 bytes of data each, so B is 03 when calling CopyRoomData. How many portholes being copied just depends on when the loop reads a termination character (FF).
	AB11	LD B,$03	Handle copying the scaffolding data.
	AB13	CALL CopyRoomData	Handle copying the scaffolding data.
	AB16	LD B,$04	Handle copying the doors data.
	AB18	CALL CopyRoomData	Handle copying the doors data.
	AB1B	LD B,$02	Handle copying the ladders data.
	AB1D	CALL CopyRoomData	Handle copying the ladders data.
	AB20	LD B,$06	Handle copying the keys and locked doors data.
	AB22	CALL CopyRoomData	Handle copying the keys and locked doors data.
	AB25	LD B,$03	Handle copying the porthole data.
	AB27	CALL CopyRoomData	Handle copying the porthole data.
	AB2A	LD B,$10	Handle copying the pirate data.
	AB2C	CALL CopyRoomData	Handle copying the pirate data.
	AB2F	LD B,$07	Handle copying the items data.
	AB31	CALL CopyRoomData	Handle copying the items data.
	AB34	LD B,$04	Handle copying the furniture data.
	AB36	CALL CopyRoomData	Handle copying the furniture data.
	AB39	LD B,$10	Handle copying the lifts data.
	AB3B	CALL CopyRoomData	Handle copying the lifts data.
	AB3E	LD B,$06	Handle copying the disappearing floors data.
	AB40	CALL CopyRoomData	Handle copying the disappearing floors data.
	AB43	RET	Return.
