I succesfully updated my passkey2 to v3 but cant update to v4 because i want to flash my euro black NDS lite and the only game i have is Brain Age (US) and only v4 supports that game ? Everything is ok until i execute K2_HW04.gba then it just freezes ? I tried many times but always same :-( Tell me if i use the game thats incompatible with Passkey2 like in mine case does it always shows two white screens... Im beggining to think whats more better to do - to buy brand new game that passkey2 v3 supports or a new passme device like datel maxmedia launcher or passcard3 - what do you guys think is smarter ???
