The code "Exchange Weapons for Health" is considered Cheating?

Effect Exchange Weapons for Health

Code While playing the game hold all the shoulder buttons and press TRIANGLE, X, SQUARE, O.

Also this other one that requires the full bar

Fireball and Frezze attack "During game, with your yellow bar full, hold down L1, L2, R1, R2, and press right, left up. This will shoot a devasting fireball and also a freeze ball."

The first one uses health and the other uses the power bar

The only one I'd say is maybe bad would be exchanging weapons for health but only because it pops a message on your screen unlike any other energy attack. Fireball and Freeze is fine as it uses energy for an attack. Personally I see nothing wrong with using either.
