Gradius Galaxies [GBA]

Complete weapons power up w/out drawbacks
This code gives you full power ups like the other two, but, unlike those, you can use it more than once per game/it doesn't kill you.

Pause the game, then press:
Down, Down, Up, Up, Right, Left, Right, Left, A, B, Start

You can use this code as often and whenever you like, with one exeption. It will take one of your extra lives in stock each time you use it, so if on your last life it won't work. It should also be noted that you get no Speed upgrade with the code, so you'll still need a couple of those.
