Emulators for your cellphone

Wired News has a nice little overview of some of the emulators that have been ported to cellphones, specifically those using Symbian operating system.  One of our favorites is ScummVM, which lets you play a bunch of classic graphic adventure games like Beneath a Steel Sky and Escape from Monkey Island.  Please,
somebody port it to the PSP.  Who needs Ridge Racers when you can have Sam and Max?
