It's been a little while since we covered the PlayStation Museum, and the site that's the "culmination of years of research and dedication to the Sony PlayStation" has been adding more neat, obscure material.

A recent exclusive is screenshots and a review of Battleship for PS1, in which you "Experience the thrill of heart pounding naval action amid the surging spray and deafening explosions of real-life combat" - an odd, unfinished and unreleased conversion, but fun to poke at.

Other obscureness which denizens of GSW may appreciate include a comparison of Slap Happy Rhythm Busters, checking out the differences between an unpublished U.S. prototype from THQ and the final Japanese version - "subtle differences like different options available, between match conversations, health bar, and more."
