I have checked these codes for mistakes (none)
I have downloaded the latest database from gbatemp to try to solve (still not work)
I am using the European version with European codes
These codes work in single player mode
These codes worked on wifi before installing the firmware
I see other players on wifi using these codes
The infinite health code still works


Thank you for your time.

sorry if this seems out of place; i was unclear on where to post this.
