Please, just download the packs available in the first post... for now, everything you've seen except Water Temple, Fire Temple and Death Mountain Crater are in those packs. When version 4 comes along, there will be even more stuff available.
The individual peoples' works are collected by death--droid and released as part of the packs in the first post (i.e. the Community Retexture Project BETA releases). The internal links in later posts really only meant as a way to pass those files along to death--droid so he can compile the packs.
In other words, everything you've seen so far in these posts (screenshots, links, etc.) are available in the packs in the first post, with the exception of Water Temple, Fire Temple, and Death Mountain Crater, which are works in progress. And the stuff that hasn't been started yet (see the list of completed areas, also in the first post).
As far as technical issues with emulators and whatnot, please direct those questions to more appropriate threads (this thread is about the retexture project, not a troubleshooting/tech support forum).
