Gradius I-IV and Gaiden compiling onto PSP

(Unemulated) PSP shoot-em-ups are getting a boost in Japan with the release of Gradius Portable, a compilation of Gradius I-IV and Gaiden, on February 9. An American/Western release has not yet been announced.

Options include saving states by pausing the game, toggling slowdown, playing in widescreen, and restarting from any previous save made. A movie gallery for PlayStation extras in the past is also planned along with a music gallery featuring soundtracks "from all five games (as well as Gradius on the X68000)." Prospective PS3 owners, expect a next-gen follow-up as well.

So are you ready to go portable and bust some alien heads? (And quite literally, too, judging by the boss pictured?) Importers, you know what to do.
