Enable/Disable Auto-optimize

Well I did this in about 10min, you can test it. You only need to change the 4 CMPs with the dirk ID (00) to your good item ID. Note that you might need to change the org $C3F091 if that free space is used by other patches, check your ROM first.

Code:

hirom

org $C39EF8
jsr free_space

org $C3F091
free_space:
jsr $93F2         ; define y...
lda $0023,y       ; relic 1
cmp $B0           ; unchanged?
bne lbl_9F6F      ; branch if not
lda $0024,y       ; relic 2
cmp $B1           ; unchanged?
bne lbl_9F6F      ; branch if not
bra lbl_9FAC      ; reequip: no

;fork: compare old and new relics
lbl_9F6F:
lda $B0           ; old relic 1
cmp #$00          ; dirk for now, change to your item ID
beq lbl_9FAC      ; trigger if so
cmp #$D1          ; genji glove?
beq lbl_9FAC      ; trigger if so
cmp #$D0          ; gauntlet?
beq lbl_9FAC      ; trigger if so
cmp #$DA          ; merit award?
beq lbl_9FAC      ; trigger if so
lda $B1           ; old relic 2

beq lbl_9FAC      ; trigger if so
cmp #$D1          ; genji glove?
beq lbl_9FAC      ; trigger if so

beq lbl_9FAC      ; trigger if so
cmp #$DA          ; merit award?
beq lbl_9FAC      ; trigger if so

beq lbl_9FAC      ; trigger if so
cmp #$DA          ; merit awarD?
beq lbl_9FAC      ; trigger if so
lda $0024,y       ; relic 2
cmp #$00          ; dirk for now, change to your item ID
beq lbl_9FAC      ; trigger if so

beq lbl_9FAC      ; trigger if so
lbl_9FA9:
stz $99           ; reequip: no
rts

;fork: set to open equip menu
lbl_9FAC:
lda #$01          ; reequip: yes
sta $99           ; set indicator
rts

Hey Madsiur, I finally tried this patch today (I had to fix a bug with a new dual-wield relic and remembered about your patch).  There is a bug with your patch, however.  I changed all the cmp #$00 lines to cmp #$E1 (my new dual wield relic).  however, in-game, whenever I use the L & R buttons to change characters while in the relic menu, it always goes to the characters equipment menu to force a re-equip.  Basically, I can't cycle through characters in the relics menu anymore.  Any idea why that is?

Edit: I don't know if a 1.1 ROM makes any difference.
