Castlevania Adventure invincibility not against spikes. this code also works with the japanese and The GBC one in the Konami GB Collection volume 1 as well.

Ninja Gaiden Shadow
Invincibilty(Flashing) except if you fall into pit.
011895C0

This code is wrong

the code for invincility on the link posted is just infinite Health since he keeps getting bumped.

You do realize that is the BSFree archives,they are old codes and only thing we can do is make new updated codes. They are there for reference and for completeness' sake.
