rrootage.jpg The Japanese freeware shoot-em-up developer Kenta Cho is much-loved for his supremely abstract, frantic PC shooters such as Torus Trooper or Gunroar. Now, an earlier piece of Cho greatness, rRootage, has been converted to the PSP as homebrew software, thanks to Mrbrown - there's more information on the PS2Dev Forums.

You'll obviously need an earlier version of the Sony handheld's BIOS to run the game, though - in fact, it apparently even still has issues for those with a V2.00 bios, though these are being worked out. There have previously been PSP ports of Cho's excellent abstract shooter Noiz2sa, but this adds even further to the frantic handheld goodness.
