Hi Townzy :>
I am new to all this too, but I d/l'ed 1.6 just today. I went to thier official site,
www.pj64.net, then on the left click on Downloads, then click on Binaries, and 1.6 is the second one down. I have only been trying to do this for 2 days, but I think pj64 is best. I got tired of my N64 freezing up, so I will try this as a way to play my games on computer. Only Perfect Dark still freezes up on me lol! (and it's hard to play wih a sidewinder)
I hope you find what you are looking for, good luck!
