This hack includes:

• +200 new animated front sprites and static backsprites with updated normal and shiny palettes (all done by myself)
• Dark Type is now physical and Ghost is now Special (phys/spec split is NOT present)
• Pokemon that evolve via trade or trade with items now evolve by 'using' said item or via using a 'Covenant Orb' (graveler/haunter/kadabra/machoke)
• Updated movepools/basestats for many pokemon that reflect up to Gen 8
• Updated attacks/effects/basepower/accuracy that reflect up to Gen 8
• Addition of routes 47/48 and cliff cave from HGSS
• A somewhat different Yellow Forest taken from Polished Crystal (with permission from Rangi ofc)
• Kanto region has been expanded to 1:1 in size with its appearance in Gen 1
• A new Pokegear App. The "PPS" or "Pokemon-Pager-System" allows the player to summon a specific pokemon to
  use HM moves in the overworld, thus, eliminating the need for HM Slaves.
  Each pager is received when you acquire the corresponding HM move.
• Reusable TMs. HMs still exist and no longer need the Move Deleter to overwrite.
• All Trainers and Gym Leaders in Kanto have had their levels increased to be similar to HGSS' curve.

• Apricorn Balls now have their own unique palettes in battle.
• The GS ball is obtained when you enter the pokemon center in Goldenrod after completing the E4 the first time.
• The Odd Egg now has a 50% of hatching a Shiny.
• Many Kanto-only Gen 2 Pokemon can now be obtained in Johto such as Houndour/Murkrow/Slugma.
• Viridian Forest/Seafoam Islands/Cerulean Cave have been added from HGSS.

Pokémon CrystalDust is a remake of Pokémon Crystal with the engine from Pokémon Emerald. See the game come to life in ways you never imagined as you experience the jump from the Game Boy Color to the Advance!

Following in the footsteps of Pokémon FireRed and LeafGreen, enjoy everything as you remember but recreated with an awesome amount of polish. Never before has Johto looked, felt, and sounded so nice on the GBA!

This game re-introduces the DNA Splicers from Black and White 2... Except this time, you can use it on EVERY Pokémon!

Use them to combine any two Pokémon together into a completely new Pokémon.
145,161 unique combinations exist in the game!

Pokémon Infinite Fusion is based on the Pokemon fusion generator.

Welcome to Borrius, a region rich with history. Centuries ago, the Borrian people were enveloped in a great war with a foreign land. When all seemed lost, the Borrian king summoned a powerful force to help turn the tide of battle. Unfortunately, the war ended in defeat when the king of the foreign land unleashed a devastating weapon. Disgruntled, the Borrian army returned home.
The people, now enraged against the Borrian king, attempted a coup by manipulating the dark force summoned during the war. The Borrian king was able to seal away its power, however, and the coup was thwarted.
Many years later, an organization known simply as the “Shadows” seems bent on releasing the dark force once again. Are they after the destruction of the Borrius region, or is there something else at play? It's up to you to stand in their way!

Pokémon Mega Blue is a rather small project, aimed to create a counterpart game for my other rom-hack, Pokémon Delta Emerald. Together, they provide a full roster of available Pokémon, so you can fill up the Pokédex playing only these two hacks.
Essentially, it's still the same FireRed and LeafGreen with an unchanged storyline (except for an addition of Ariana and Archer), but updated mechanics, Alola Forms and Mega Evolutions (the latter two are mostly in the post-game, though).
