pokeemerald VS Complete-Fire-Red-Upgrade

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

I came across Skeli789's Complete FireRed Upgrade hack and really just wanted to play the base hack without any additional modifications. The instructions seemed straightforward enough, but I really didn't want to have to install additional software for a one-time use, and I wasn’t really sure how to set up the offsets or if I even needed to. I really just wanted to be able to run a simple script, create the rom, and play! So I set out to make compiling just the base hack itself simple for me and everyone else!

Do you think HMA would work with a rom that's been patched with the Complete Fire Red Upgrade that was used to make Pokemon Unbound?

Definitely definitely look at doing your project as a decomp using pokefirered or The Complete Fire Red Upgrade.

The Battle engine is custom. Should use Gen VIII movesets though.

But the "Dray Hacks" From the ROM hack author Drayano (the author behind Storm Silver, Sacred Gold and others) seem to work with Pokélink absolutely fine. Unlike ROM hacks like Pokémon Unbound and Radical Red for example. Reason: Adding support for new games/ROM hacks and/or new main-series titles requires a lot of time and effort. (We're talking many months, full time - for example) I can go deeper into this if you want, but hopefully this explains enough for now :stuck_out_tongue: This is due to the fact that Drayano rom hacks changes aspects (such as story-line, IVs and EVs) things within the game - but doesn't change how the game stores data in memory when playing through the game! As opposed to how ROM hacks such as Radical Red change where the data for the game, is stored in memory during game-play. (If you want a deep-dive, these two Rom Hacks use a modification for Fire red called CFRU https://github.com/Skeli789/Complete-Fire-Red-Upgrade which changes a lot in game)

I'm guessing you're talking about this romhack based on a decomp project? https://github.com/Skeli789/Complete-Fire-Red-Upgrade

CFRU's AI and quality of life

There is also the CFRU (Unboud and Radical Red are made with it). It is C code that is injected into the fire red rom and edited with normal binary tools.
