R-Type DX Cheats (GameBoy Color)

To unlock the De Souza drawing editor, you must finish the color-enhanced versions of
R-Type I and R-type II as well as R-Type DX. Then, at the main menu, push the d-pad RIGHT
- the De Souza drawing editor option should appear!

To skip a level you've already completed, pause the game then press B.

To restart the current level, hold B and turn Game Boy off. While continuing to hold B,
turn it back on again. The game will resume at the beginning of the last played level
with five ships, no points or power-ups.

For invincibility, complete R-Type DX using no more than 10 credits. Then, during a non-DX
game, press Select + A.
