The retro C64 emulator Frodo 1.5 now includes improvements such as accelerometer support (which lets you simulate a joystick by tilting the phone) and an on-screen keyboard. The S60 3rd Edition version of Frodo works with all N-Gage-compatible phones, though only some of them support the accelerometer function. You can find Frodo and other emulators, as well as lots of S60 games, in All About N-Gage's Unofficial Games section. You can see a demo of Frodo's accelerometer support below.
