Honestly I'm not a huge fan of it. Like it's alright, but boy there's way too many Pokemon crammed into such a small space. Sacred Gold and Storm Silver felt a lot better, and I guess that's because there's two regions to spread everything out across. Getting one form every generation of starters before the second gym is OP as heck, as well as getting access to pre-evolutions to pseudo-legendaries so early (which I think is a problem with SG/SS as well).

His hacks are good, but I think they all suffer the same balancing/cramming issues which kinda kill the whole... genre? of hacks for me, GBA 386 hacks are already somewhat pushing it, but 493 is a bit much I think.
