Megaman Zero 4 codes ( 100% working but still glitched )
US version enable code: 0000D460 000A 101269E8 0007
Jump to the end of the intro level 72036656 0002 82036656 0010 *Just a lil' code here, this code can kill you if you leave it on in after the intro level, 'coz it's a level section jumper.
Jump to the boss in Area Zero 72036656 0002 82036656 001D *Should only use this one in "Area Zero", to jump straight to the boss. Since it doesn't give adequate time for the tiles of that area to load, the boss might look a bit odd..
Extra rapid fire buster 32036748 0001
Rapid Fire Specials! 32036700 0001 *Now you can rapid fire stuff like lasers and even the move to grab weapons! Err, Ok well you have to throw away your weapon from in the start menu, or else the game might crash. It can't be helped since there is no 8-bit "if" type code for GBA.
