Some patch for Emerald

[Yave Yu]

I wanna share some patch for Emerald, it (may) compatible with all tranditional binary 1986 ROM based hack, but incompatible with all decomp hack.
The first one is Pokemon, bag, and money data decryption.

 

[Yave Yu]

Optimized some game code to run faster… maybe😂

 

[Yave Yu]

When battle begins, the background, character, and ground are move faster.

 

[Yave Yu]

Catch a Pokemon give EXP like defeat it.

 

[Yave Yu]

Pokemon now can gain all six 252 EVs, also modified single EV cap to 252.

 

[Yave Yu]

Nature influence now fill with color, red is up, blue is down.

 

[Yave Yu]

Battle text stays more shorter.
If some hack adds new battle text, it may not reduce their delay, because they are new, non-vanilla location.

 

[Yave Yu]

Saving game no longer tell you there already has a savefile, it's really unnessesary.

 

[Yave Yu]

Continuous repel system now in Emerald, for some reason none of Emerald hack really implement this, including decomp hack, they instead give you a box to choose a repel.
It won't work on some emulator, will softlock after use a repel. They are:
Newer VBA-rr
VBA-Next
Older VBA-M less than 2.1.1
(As well as older GBA.emu)

mGBA, MyBoy works fine, other emulator such as Delta (iOS) I don't know.

 

[Yave Yu]

Redirect key item fanfare to another existing song, for some reason Emerald didn't use it.

 

[Yave Yu]

Increase money cap to 9999999, match BW (and onwards) standard.
Emerald uses different text format compare to FireRed, so if let it store 999999999, text would look weird.

 

[Yave Yu]

Flash now lighten entire screen, don't influence that gym.

 

[Yave Yu]

Change default settings, text speed from mid to fast, sound from mono to stereo.
If some hack modified these options, don't use this patch.

 

[Yave Yu]

Naming now auto switch to lowercase if the first letter is uppercase.

 

[Yave Yu]

Low HP beep now just ring 3 times.

 

[Yave Yu]

Hatch from egg begin with Lv1.

It's great to hear that it has the potential to be compatible with traditional binary 1986 ROM-based hacks, even though it may not work with decomp hacks. The ability to decrypt Pokémon, bag, and money data could be very useful for those who are working on hacks or trying to modify the game's data. I'm sure this will be appreciated by the Emerald hacking community.
