[ASM & Hex] [EM] Reset Mossdeep's rocket launch counter?

[tkim]

I would like to reset the player's rocket launch counter. Here's the routine called by special2 LASTRESULT 0x103 which reads the player's current rocket launch counter:

sub_8138BDC: @ 8138BDC
	push {lr}
	ldr r0, _08138BFC
	movs r1, 0
	ldrsh r0, [r0, r1]
	movs r1, 0x7
	bl __divsi3
	lsls r0, 16
	lsrs r0, 16
	ldr r1, _08138C00
	cmp r0, r1
	bls _08138BF6
	adds r0, r1, 0
_08138BF6:
	pop {r1}
	bx r1
	.align 2, 0
_08138BFC: .4byte 0x03005cf8
_08138C00: .4byte 0x0000270f

This routine reads off of a ram offset and then stores up to a maximum value of 0x270f (9999) to a var such as LASTRESULT. I would like to edit the value stored at the ram offset itself, but I don't know how to figure out the ram offset location.
