Somehow I think one of the 1000's of overclockers on this forum would have mentioned if blue smoke came out of their phone by now. I run mine at 800MHz consistently and 950MHz for gaming and I've not had any issue after 6 months... much the same to the many people I know that overclocked (several at 1150MHz)

This is CERTAINLY the phone for you if you love retro gaming, especially RPGs. I've beaten Chrono Trigger, FF1 & 2 on SNES, Pokemon TCG on GB (lol :P), Super Mario 64 on N64 (this game is fully playable, as are plenty of other games on N64) and gotten a significant distance into FF7 on PSX emulator (before I forgot to backup the save when I deleted it :S).

Realistically if you are after a retro machine I couldn't think of anything better than an N900, TV out and a PS3 Controller (or Wiimote.. but this'll be a fair bit more to get working properly).

Finally, sooner or later when next revision of N64 emu becomes available we should also see Starcraft 64 running fine too if you need a Starcraft fix (and Stargus doesn't satisfy).

Finally 2, of the emulators, the NES one does the job fine, as does MAME and GBA (although I've only tried a couple of basic games with it).
