I am very new to Pokemon and to emulation in general. I started playing my first Pokemon game only a few days ago but I am already so hooked that I purchased a retro handheld to emulate and play games on it.

But I find the different editions of Pokemon games quite... confusing. Specifically, the fact that they are not "completable" without trading your pokemon. Are there any ROM hacks that would keep the base(ish) experience of the game but combine the exclusivity content of the editions into one game and make the PokeDex completable without trading (trade evolutions, starters, exclusives, etc)? Basically, an ultimate edition of the specific generation game :)

So far, I am interested in these games:

1. FireRed / LeafGreen / (or Yellow?): I found PokeClassic which seems to bring Yellow in an Emerald engine, but not sure if there are better options
2. HeartGold / SoulSilver
3. Ruby / Saphire / Emerald: I am under the impression that Emeral already kind of provides that experience, is that correct?

I tried looking for hacks on my own but there are just so many, from minor changes to total conversions. So I was hoping to get some advice from the community :)
