The problem with most of the PSP homebrew releases has been that ruddy bug that forces you to take your battery out then back in to exit a game but now thanks to <a href="http://forums.ps2dev.org/viewtopic.php?t=1723" target="_blank" >PS2 Dev Forums</a> all new PSP homebrew releases can by via the Home button go back to the menu, the earlier releases of Simpleturn and Trivia had that feature enabled and now TetrisJP v1.2 does also, download this latest version at our page here --> http://psp-news.dcemu.co.uk/tetrisjp.shtml
