Hey guys, I love that people still like the hack. Thanks a bunch, really! :D
Since my comment was buried in the page before, I would like to restate that I can't do anymore improvements on this hack... however! Do not fret one bit newcomers! I had designed this from the start with this eventuality in mind, and made it completely able to be played through from the start! Essentially outside of a few bugfixes I could have done, this was done a long time ago. I'm also still available for questions if you would like to shoot me a PM, I'll get to you soon as I can. :D
If you wish for further improvements from this hack:
1. MrDollSteak's rombase, which was used prominently in this hack, still lives. You can find it here, as well as a list with some bugs which should be added to my own:

2. A looong time down the road (we're talking not weeks or even months here, I'm unsure), I would like to start this hack from scratch. Why scratch, you may ask? Here, let me tell you what I have in mind...
-Over the time of this hack, some improvements were made which I had taken note of and would learn from (for example G3HS is now a thing which affords me a new boon I will touch on further down), but I couldn't really implement properly. Also, since the start of this hack I have a different opinion on the Fairy-Type. I couldn't just add it with everything the rombase had with it this far in.
-Better documentation. This is a very hazardous flaw that I made which led to crap like the Pokemon Data List debacle on my part, as well as making "what other patches work" as nothing more than a guessing game. I apologize for that.
-Gen IV evolutions, let's face it this hack was pleading for them. Looking back the way I handled stats of certain Pokemon was poor. I could do this before, but my initial thought was that these Pokemon should have had these boosts from the start. This was silly as I was melding two movesets into one and some postgame Pokemon became a jumbled mess. As an additional point, with G3HS I can now more easily than before implement things such as having Eevee evolve into all forms in one hack, AND make it so no replacement is required in the Pokedex for those who want to hack in their favorite Hoenn 'mons (also, you can do this without an ini file now).
-Optional patches, for neat things like an RTC/Day and Night, EXP gained for catching, reusable TMs, disable overworld poison damage, or D/P style PokeMarts for those who want it (maybe if I'm lucky, day/night encounters will be more feasible?) Gen IV evos can be put in optional for those who want a pure 251 experience.
-I could possibly, if a more stable map editor is available at the time (A-Map 1.95 was my main reason for not doing this), expand the ROM. I could add some optional things which don't detract from the core experience this way like decent event maps for those Legendaries I added or something. I could also use this to expand the Pokedex further for some other entertaining optional patches... but that is a pipedream so far.
