Pad Method [cop0] 0188c943 Works on 95% of GBA Games!
Occasinnaly you'll run into more then one ref so you need to do some testing, but I did the testing for you and here are acceptable refs 43c98801 (cop0) $03c98801 481e8011 cop2 $001e8011
and if that happens a couple times then these ops to garrentee it 43c98801 (cop0) $03c98801 481e8011 cop2 $001e8011 4a1e8001 vaddy vf0, vf16, vf30y
*Make to make sure everything is clear the address with the value and ops (cop0) $03c98801 is your Enabler Code.
**Depending on your version of Codebreaker Advance this enablers might not work but thats it taken care of because once again I did the testing for you. All you need to do is either add 2 or 4 to your address and your done. You now can make an offical Codebreaker Advance Enabler Code.
Here are some examples and prove that my method does indeed work... ALL GAMES ARE NTSC UNLESS NOTED!
