That most be one of the all-time biggest phallacies (that uHLE can run Zelda (near)perfectly. It was (near)perfect for 1999, but for 2002, no thank-yee.
No, i recommend he buys the cart. But if he was prepared to drop to "near perfect" or "OK given suitable system and configuration", then i'd recommend PJ yes.
UltraHLE? Ok, here are my specs:

Is there any way I can modify the controlls on UltraHLE?
AHHHHHHHHHHH!!!!! no offense but those specs totally suck. especially yur video card lain: try to get a glide wrapper at there official site http://www.emuunlim.com/UltraHLE try to get one that has ati rage on it or just try the closest (cause ati rage is TOTALLY out dated) go for a wrapper that supports ati rage pro and that'll be the closest.
Or just get SupraHLE 1.1.1 and its configurator (included). It'll bring you all the wrappers & options & help you need for an easy step into N64 emulation.
