DEMO Format (Fury of the Furries)

The DEMOx.BIN file of Fury of the Furries stores keypresses used when the game is playing by itself in 'attract mode'.

There are three levels of the game played in rotation during attract mode. The keypresses are stored in DEMO1.BIN, DEMO2.BIN and DEMO3.BIN.

Each file consists simply of sufficient bytes to see the player through until the point where they die in the level. The game runs at 30 frames per second, so 30 bytes are required for each second of gameplay recorded in the file.

The 5 least significant bits of the byte each represent a single key, when the bit is set, the key is pressed, when the bit is not set, the key is not pressed.

Bit	BitMask	Key	Description
0	0x01	LEFT ARROW	Move left.
1	0x02	UP ARROW	Jump / Move Up.
2	0x04	RIGHT ARROW	Move right.
3	0x08	DOWN ARROW	Change Form / Move Down.
4	0x10	SPACE	Furry special action; Fire, Eat or Swing.
