Ironically, it broken in current build but you can use one of the older 1.7 builds (there's a whole bunch). Right now, I use 1.6 and Jabo 1.6 (Jabo 1.7 is not backwards compatable). But I don't think it's any better now though; except the menus are not squished as opposed to Jabo 1.6. Don't use 1.5.2!!!! I don't understand why people don't realize just how much better 1.6 is over 1.5.2.
If you are a 64 emulation fan though, I think PJ 1.7 is worth the 20$, especially given it won't officially come out until 2008.
