universal-pokemon-randomizer VS pokeemerald-expansion

You might also want to use Brentspector's fork, or some experimental branch of ZX, if you are looking for specific features. Though the former is slowly falling more behind as afaik Brentspector has stopped working on it, and experimental branches can be buggy and have to be built before using.

This version of the UPR works with FireRed Randomizable 809.

Randomizers generally don't like ROM hacks, unless they are built-in of course like with Unbound. The Universal Pokémon Randomizer (UPR) relies on manually entered offsets for ROMs, like where tables for all the data are found. (for examples, look in the .ini files here) It is possible to enter these offsets for ROM hacks too, but afaik it has only ever been done to Gaia, Randomizable 809, and a few Speedchoice ROMs.

There is, in Brentspector’s branch.

Brentspector’s branch of the UPR should work with FireRed 809 Randomizable (not to be confused with 898 Randomizer!).

Gaia can be randomized with its own customized randomizer, and FireRed Randomizable 809 can be as well, with the best support in Brentspector’s branch of the UPR.

If you have a ROM hack you want supported (and it's Gen 3), then yes. This will also enable adding in support for Static pokemon. There is no full list of possible overrides, but most can be found between the Fire Red 1.1 (U) in gen3_offsets.ini and the gen3_hack_offsets.ini file. Let me know if you want more details. I'd love to expand support for more hacks.

Overview: The Battle Hacktory aims to enhance and expand upon the vanilla Battle Factory experience using RHH's pokeemerald Expansion v1.6.2 https://github.com/rh-hideout/pokeemerald-expansion/. For those unfamiliar, the Battle Factory is a draft format where you pick 3 Pokémon from a draft of 6 Pokémon with the goal of making the best team possible to win 7 consecutive battles. After each victory, you will have the opportunity to trade one of your rentals with one from the defeated trainer. In addition to this, you get some scouting information about your next opponent's team allowing you the ability to counter-team your opponent to an extent. This mechanic allows players to gradually build a formidable team as they progress through sets of 7 battles.

This is a demo for an implementation of Dynamax for RHH's next update to pokeemerald-expansion! Raid Battles haven't been made yet, but are on the way.

Definitely decomps. The games have been completely broken down and rewritten in C code so you have the ability now to edit anything directly with C rather than all the hex editing that was required before. PoryMap is a new mapping tool to go along with the decomps that’s much better than AdvanceMap. Along with the link already provided here’s another about the Emerald decomp specifically: https://github.com/rh-hideout/pokeemerald-expansion

Not sure if there are any new effects but pokeemerald-expansion does assign contest effects to all added moves.

Are you talking about the one with SacredAlmighty? It is some custom version of Emerald decomp as far as I can tell, probably based around RH-Hideout’s Pokeemerald Expansion.

You can look at the pokeemerald decomp. Instead of using binary tools like Adcance Map and HMA you are editing the source code with a simple text editor and porymap. The pokeemerald has everything up to gen8 (mons, moves, abilities). An example hack that was made with the decomp is Inclement Emerald.

One of the benefits of the decomp projects is that people host their work on GitHub and there are a ton of open source feature branches that are available for you to merge into your project. For example the pokeemerald-expansion adds Mega Evolution, Primal Reversion, Fairy Type, Physical Special split, Alolan forms, all Pokemon and items and TMs and abilities up to Gen 8. All in a project base that you can build off of and create your own hack with. Its crazy.

Oh sorry, that was all the work of the rh-hideout community who have ported much of the later gen battle mechanics into an emerald decomp expansion project
