Raiden Legacy cheat codes:
When you die, you drop a series of power-ups - be fast
and you can collect these when your ship respawns.
Reserve your smart bombs for moments of dire need -
they're ideal for getting out of impossible situations.
Select any ship, if the ship is on top, hold up and if the ship
is on the bottom, hold down. Then press start + fire button + bomb button
at the same time to unlock the Slave ship.
The ship's speed depends on what ship you're using.

Unlock All The Ships:
To unlock all the ships, go to the machine's Test Menu. Enter "Game Settings",
change everything to 9 on "Shooter1 Coin/Credits" and "Shooter2 Coin/Credits".
Also turn On "Free Play". Now exit that menu and go to "I/O Test".
Hold the Test and Service button and repeatedly press the 2nd player's Start
button. If done right, you should see the "Days of Operation"
counter increasing. Set it to over 140. Exit that menu and reset
the "Shooter1 Coin/Credits", "Shooter2 Coin/Credits" and "Free Play"
if you wish. You can now exit the Test Menu altogether and reboot the machine.
If done right, all the ships will be selectable.
