Welcome to Pokemon Emerald Final, this started out as something for personal use, but I continue to improve it. The goal of this ROM hack is to make the ultimate enhanced vanilla Emerald

About this Version:This has been a long, arduous journey but it is now ready to release! v7.41 Has some bug fixes and some fun new features I am pretty excited about (detailed in the "New This Version" section) and some fun stuff planned in the future. Shouldn't be nearly as much trouble for future versions as the main issue with this one was bugfixing. For those interested in knowing, the BAD EGG bug was caused by the Surf script of all things... Fortunately that has been fixed! A big new thing worth noting is there is now an item for using Fly which makes traveling around the map much easier. About Compatibility:As always, Emerald Final is compatible with Vanilla saves, however the Deluxe Variant's saves cannot be imported back into Legacy or a Vanilla ROM unless all new generation moves are deleted. This also means Vanilla link compatibility exists so long as no new moves are involved in the trade / battle.Saves will transfer between both versions of Deluxe no problem, and from Legacy or vanilla into Deluxe.

Differences Between Deluxe and Legacy

Deluxe uses the Battle Engine Upgrade v1 by DizzyEgg, which I have used to add in modern mechanics and 4th gen evolutions, abilities, and moves. There are a few visual bugs but nothing gamebreaking. Also the recharge moves like Hyper Beam had to be changed to recoil because they wouldn't function properly. Legacy has all the features minus Gen 4 additions.NOTE: Only use the optional patches for the variant you opted to use! They are not mutually compatible.

New This Version:De-Evolver.151 New Tutors (most are Deluxe only).New items.Wild Pokemon have been changed around.Merchant in the BP Exchange at the Frontier sells items needed for Tutors.Bike anywhere indoors.Small merchants added to Dewford and Pacifidlog's Pokecenter with simple inventories.Gen4-Style Sprite Replacement option.Pokeball Replacer in Contest Hall. Pay a fee to swap the type of Ball your Pokemon is in.Shiny Charm: In an out-of-the-way location, there is a Charm that increases the Shiny Rate.The final rival battle's starter is now fully evolved.Updated TM compatibility: Pokemon like Manectric had their TM compatibility changed in later gens and they have been updated to reflect that.

Features included:

The reason for it being 2 EVs is since the points give a stat point at every 4 EVs, so you can use the Macho Brace to have it be one battle per stat increase. There is also an NPC to heal your pokemon and show EV/IVs inside the cave.
