Doesnt really matter that its only one entry. PJ64 is known as one of, if not the, best N64 emulator. Its open source, and ported to the xbox, with a devoted developer doing daily progress....what exactly would competition accomplish? Nothing. It wouldnt change a single aspect of his coding. If anything it would hurt things in this situation.
Its expected to get whiners and complainers. Its NOT expected, and certianlly not appreciated to get it on such a large scale. It accomplishes absolutly nothing, except for discouragement.
Like someone said, the only reason there is a appreciation thread is because everyone knows there's just going to be a excessive amount of bitching.
