	7x	hit from below
	8X	jump on
	9x	jump on / hit from below
	Ax	touch any side
	Bx	touch from front

	treasure initiator (if byte 2 = 1x)
	1x-Cx	same as event initiator values

	battle initiator (if byte 2 = 2x)
	bit 0	fight formation #$001 (Terrapin x1)
	bit 1	returns after entering area again
	bit 2	is not removed when defeated in battle
	bit 3	returns after entering area again
	1x-Cx	same as event initiator values

byte 10	lower bits: object offset (if byte 2 = 0x)

		    star XP increments (if byte 2 = 1x) (read from 0x39BC44)
			x0  monsters give 1 XP
			x1  monsters give 2 XP
			x2  monsters give 5 XP
			x3  monsters give 8 XP
			x4  monsters give 13 XP
			x5  monsters give 11 XP
			x6  monsters give 0 XP
			x7  monsters give 5 XP
			x8  monsters give 6 XP
			x9  monsters give 9 XP	

		    movement offset (if byte 2 = 2x)

	upper bits: formation pack offset (if byte 2 = 2x)

			0x  Mushroom (restore all HP/FP)
			1x  Invincible Star
			2x  Flower (max FP +1)
			3x  Frog Coin
			default is an item byte, but usually the event script declares the item

byte 11	X coordinate
byte 12	Y coordinate
byte 13	bits 0-4: elevation (up to 0x1F)
	bits 5-7: radial position

	60  down-left
	80  left
	A0  up-left
	C0  up
	E0  up-right

bytes 10-13 can be subsequently repeated (with different values) for each multiple object
