Kanto at its max (and beyond!)
This is a difficulty romhack of Pokémon Yellow featuring much tougher battles; complex dungeons; restored content; more elaborated, deeper, and darker lore and story; completely new areas and story arcs; virtually infinite post-game content; a plethora of customization and randomization options.
The project is close to completion, but still work-in-progress.

- pret (Pokémon Reverse Engineer Team) first and foremost, as they enabled me to work on this project in the first place
- Vortiene, for their invaluable help, suggestions, teaching, and support over the months; this game would have likely never seen the light of day without their help (their contributions include, but are definitely not limited to: code to give trainers' Pokémon Stat Exp; code to have the elevators' wirring depend on the number of traveled floors; code to expand the number of hideable sprites; code to allow instant re-usage of Repellent; directions on how to free needed memory; too many to be counted times when they taught me about assembly, Game Boy architecture, and RBY framework)
- jojobear13, for their precious technical insights and open-source bug-fixes (the code to give trainers' Pokémon Stat Exp was originally developed by them; they provided fundamental insights on a pesky TM-related bug; they implemented a new and better RNG)
- Porygondolier, not only for being a very pleasant and interesting person to interact with, but also for working with me on the mid-battle evolution (admittedly, they did most of the job!)
- Sanqui, for granting usage on the gen1-style sprites used in their Pokémon Red randomizer; all sprites that are not the original 151, Kleavor, Annihilape, Mega Evolutions, Anomalies*, MissingNo, or taken from Gold/Silver, are taken from their project; detailed credits to single artists can be found on their website
- Plague Von Karma, for some suggestions on speed-ups, providing the move deleter/relearner code (which uses code from jojobear13, based Mateo's code), as well as Kleavor and Annihilape sprites (I modified the latter)
- FrenchOrange, mauvesea, and LJSTAR, for their many many improvements and fixed on the sprites I drew; FrenchOrange drew the Flying Pikachu sprite
- Xillicis, for their tutorial on how to increase the number of usable Pokémon, as well as many useful exchanges over the months, and for some backsprites: Electivire, Tangrowth, Rhyperior, Lickilicky, Magnezone, Porygon-Z, Magmortar
- ZetaPhoenix, for the TM name displayer code
