Downloading older versions of PJ64

[Szymon7022]

Hi.
I was playing a rom hack called Waluigi's Taco Stand. When I stomp on a goomba my game crash. I heard that is a problem with PJ64 2x and you need to use PJ64 1.6, but I can't download it now, because it's no more on PJ64 site. And there's another problem, I was playing Super Mario 64 Randomized and when I tried to enter Vanish Cap stage, the game crashed too, but it's not a big problem, because I don't need to use Vanish Cap anywhere in my Randomization Seed, but I want to get an extra star, and I was wondering will the game crash on older version. Plus PJ64 1.6 had 16:9 screen resolution option, but I don't feel bad about playing in 4:3.
Anyway, is there any way to download PJ64 1.6 from official site, not from other sites ? This is just being careful.
Regards.
