Sorry about that, it was a simple typo.

lis r12, 0x8034
lhz r11, 0x3E80 (r12)
andi r11, r11, 0x0880 #And Immediate, Logical AND using r11 & 0x0880
cmpwi r11, 0x0880
beq- the_label

Here's a simple code I made using ASM for button activator/deactivator - http://mkwii.com/showthread.php?tid=893 (source below is for NTSC-K specific version, haven't updated that particular source to use macros for region variances)

So I looked at your ASM in that code, and there was 2 things that confused me. First off, with this:

and r0, r11, r7 #Logically AND the contents of r11 & r0, store result into r12
cmpw r0, r7 #Compare value of r12 to r0.
beq- set_regionoption1 #If equal (activator is pressed), jump to set_regionoption1 label


^Your #notes don't even match up with the source ASM, specifically it saying your storing it into r12 when clearly it is being stored into r0, which your #notes say is being ANDed with r11.

Secondly, this isn't an andi. instruction, but a simple AND instruction. So is this the right way or do you actually use andi.? Also you typed (andi.) as (andi) which is actually incorrect.
