PspStates is cool… You can save the state of any game, at any point in the game, and resume from that exact state later on. The PSPgo offers a similar feature; however, you’re limited to only 1 game and 1 save state at a time. Dark_AleX’s version — yes Dark_AleX is the PspStates originator — lets you save up to 9 game states, for different games, using different key combos.
The problem? Remembering what key combo was used for what game. That’s when plum comes in, creating convenience by adding a PspStates menu system. Press the Home (or PS) button and then R+L Triggers to bring up said menu. From there you can select your slot by pressing Circle or delete a save state by pressing Triangle and X closes (or backs out) of a menu.
Activate both pspstates.prx and states_menu.prx in seplugins/game.txt. Enjoy
