ok, er...wow. you dont need a key combo on the pointer setup, you can leave that on.
perhaps giving total customization was a mistake, based on what you posted last, this one will do what you want:
Code:
[Sacred Wine - 04010302]
80000300
580F0000 08497ef0
780F0000 00000010
640F0000 00000000 0000027D
580F1000 00000008
780F0000 00000020
640F0000 00000000 04010302
20000000
i created and tested this one on my switch. so at min, you would leave on the Magnus Pointer setup code and this one.
go to the magnus you want to edit, press Right or left on the right stick to get the sorting dropdown, press ZL+ZR, then press B, the card at the bottom should change.
