I'm glad you are doing this, though I confess that, to date, the only versions of Raiden I like are the arcade, PSX, and PC versions. I suspect it is because Raiden isn't an especially original game, and what made it great was that it was the sum of so many little details, like good animation, sticky decals, and little fragments of everything you destroy flying all over the place.
Still, this adjustment might make me want to give this game another look on the PCE.
