Not like it matters because 5 people in the world will download that game, but, you dont want to use the light gun. Trust me. Its inaccurate, and clicking the trigger like mad will tire your finger/be annoying and loud as hell.
Super R Type is the best one in the series. This is of coarse my opinion. Despite the reviewer, R-Type is much easier than Graduis. The Hard difficulty however, will make you curl on the last stage. The game has cheat codes, and is worth checking out if you are a fan of this genre. If you like the music, it has a sound track section, this was very common for SNES games back in the day.
The only thing that offends me is the lack of VC games we're getting. Last year was a much better year for VC. This year they just don't give a sh!t.
