Hey guys! There's a misprint in the Achievement description of the 2 Arcade achievements to Raiden 4... It says no contines allowed in these runs... this was a translation error. I have the xbox 360 version of this games as well and thought it strange that they would allow continues on one version and then not the other... So while making my Light run and dying at the final boss... I decided well lets finish it just for fun... I got the achievement anyway! So it is indeed a misprint; and you can spam that continue till your blue in the head for the entire runs! Both on Light and Normal! So once you unlock the modes, anyone can get these achevements! Really no skill invlolved anymore that this is known! Happy hunting!
