[ASM & Hex] [EM] MWisBest's colored stats display

DarkRaichus · Nov 9, 2019

I combined this into 1 routine and cut the total size down a lot. All credit to DizzyEgg of course, this is nothing compared to creating the mod in the first place.

Code:

.text
.thumb
.thumb_func
.align 2

@ [B][COLOR="Red"]0x1C379E: 02 30 00 4A 10 47 XX+1 XX XX 08[/COLOR][/B]

main:
	@ at this point... r0 contains our return address (- 8). Convenient!
	push {r5-r7}
	
	@ save return address for later.
	mov r6, r0
	add r6, #0x8
	
	@ to determine what function we were called from:
	@ if it was right stats, r9 is 0. if it was left stats, r9 has something in it.
	mov r7, r9 @ can't really use hi registers in thumb, mov it down.
	@ so, to check the function type: cmp r7, #0. eq means right stats.
	
	sub sp, sp, #0x20

This routine highlights the numeric values of increasing/decreasing stats, but I would like for it to highlight the stat labels instead (ex. ATTACK, DEFENSE etc). How can I approach this? I will also donate to anyone who can do this for me.
