Feature request: emulation of Sleep Mode

[670839245]

although rare, some games have features that require players to set the PSP in sleep mode, and wake it up either at a particular time or after long enough to gain ... what we call idle progress nowadays. Like Idol Master SP, for example (go to the Wikipedia page of that game, and search for text "self lesson".).

Plus, maybe add an option of manipulating the system time of waking up, as sometimes players can't bother to wait that long or can't time the waking-up properly (especially when the game's system time differs from the real time before it goes sleep!)
