This hack is awesome, it has all pokémon of gen 1 (not all legends are available (yet?) ) multiple of gen 2 and 3 an of course all (pre)-evolutions. He added some Mega-evolutions (but most will be available from beta 9) The first part is based on the manga and the orange islands-arc is made by him and many 1st gen poké's can be encountered with a special color palette, he also has made some changes to typings (glitch and fairy) and bonus chapters often include some special/rare pokémon. The reason you got stuck because of a Farfetch'd was probably because it was the end of the beta? I didn't play the beta back then I think ... if not you're probably thinking of another hack :p
The .rar file includes a "pokédex" with (almost) all poké's and their locations
