Did this for a customer. It's shipping today!

Sony PlayStation, with mods:

* Stealth modchip, disables copy/region restrictions. Play burned/foreign games.

* Dual Oscillators (DO) mod - not to be confused with DFO / Dual Frequency Oscillator mod. DO cuts the GPU's NTSC clock, replaces it with the correct 53.693175MHz clock for accurate timings on USA/Japanese games. PAL clock input (still wired, hence DO) is 53.2MHz; the GPU has pins for both.

I invented the DO myself! (again: it's not DFO)
