Emulation on the N-Gage: Is it worth it?

[Querjek]

I'm pretty sure I heard someone mention this before. What's the deal with emulation on the N-Gage? What is required to emulate stuff on it, and how much will all of this cost? I'm pretty sure I'm going to pick one up semi-soon, and wanted to know if the emulation is worth my time.

The N-Gage does Nes and pre-nes stuff pretty good.
Mame is also coming along nicely.
Most of the emulators are free and it's just a matter of downloading them and then copying some roms to the N-Gage.
