Slightly off-topic, but related to earlier posts; I took the time to install Daedalus X on my ageing PSP 1001 last night, and I can confirm that with some minor tweaking, Ocarina of Time is perfectly playable on it, and looks great on the PSP screen, the PSP analog stick also works really well with both Oot and SM64.
You can probably pick up a PSP for less than $50
