Well, i need at least 10 posts, let's share my work
With this code, the game will act as if you repeatidily push the button while you push it down
_C0 FastButton
_L 0x232D09 0x0
Basically, with this code, you'll get like a laser of shot :D, destroy every enemy within a second
_C0 Unlimited Fire
_L 0x232CF0 0x0
_L 0x232CF4 0x0
_L 0x232CF8 0x0
(note: do not work with charged fire, anyway, they'll become useless with this, normal fire is powerful enough)

Wanna try the XBuster or ZBuster ?
_C0 X Full Armor (XBuster)
_L 0x232D01 0xF
_C0 X Full Armor (ZBuster)
_L 0x232D01 0x2F
with this, try both of them
