pokeemerald VS universal-pokemon-randomizer

When you start a new game, the game generates the Dewford phrases (and Feebas tile seeds) from EasyChat words by making some calls to RNG, shown here in InitDewfordTrend and SeedTrendRng. To summarize (assume H16 is the upper 16 bits of the RNG seed on that advancement): It makes a call on Advance x to determine the first word, always pulled from CONDITIONS (H16 % 69) It calls RNG on Advance x+1 to determine whether the second word is from LIFESTYLE or HOBBIES (H16 & 1, LIFESTYLE if it's 1, HOBBIES if it's 0) Then it calls RNG on Advance x+2 to determine what that word will be (H16 % 45 for LIFESTYLE, H16 % 54 for HOBBIES) It calls RNG on Advance x+3 to determine whether the trendiness is increasing or decreasing (not important for this, but it's H16 & 1) It calls RNG on advance x+4 to try setting the maximum trendiness If this value is greater than 50, it calls RNG again (on advance x+5) to try setting the max trendiness. If this value is greater than 80, it calls RNG a third time (on advance x+6) to set the max trendiness (each of these calls are H16 % 98) Once it has the max trendiness (takes the result from above and adds 30, giving a max value of 127), it calls RNG to set the current trendiness (the value itself isn't really important for our purpose, but it's (H16 % (max trendiness value+1)) +30, where the max trendiness value is the value before adding 30. This value also has a max of 127) Finally, it calls RNG to set the associated Feebas seed (H16)

it's used for working with decompilation projects like pokeemerald

This is the main one: https://github.com/pret/pokeemerald/wiki/Adding-new-event-object-or-overworld-sprites

I strongly recommend you to switch your project to pokeemerald as it's more difficult to get those bugs. Also you'll get some tutorials in its wiki.

There are several reverse engineering projects out there which perfectly reconstruct 1:1 accurate C code and compile to the exact same bytes given the original compiler. Please see https://github.com/pret/pokeemerald . Of course you lose names and comments but it is not accurate to say no to this question here. It's perfectly possible to construct recompilable matching C code (purely in this narrow case, anyway.), it's just really tedious and a question of permutation through sets of C fast enough to find a matching member.

You could start by looking at the decompositions like https://github.com/pret/pokeemerald and seeing what resources they have, but it’s gonna require coding and it’s not as drag and drop.

Pokémon Ruby/Sapphire, Pokémon FireRed/LeafGreen and Pokémon Emerald.

I don't know about any sort of translation, but if you're trying to do something specific, you generally try to think of a place in the vanilla game that already does it and check out its script file to see how it works. You can see all the event functions (or macros as they're called in the files) here: https://github.com/pret/pokeemerald/blob/master/asm/macros/event.inc

With enough dedicated people it doesn't have to be, https://github.com/pret/pokeemerald

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.
