《宝可梦绿宝石》数款二进制改版补丁分享

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

Continuous repel system now in Emerald, for some reason none of Emerald binary hack really implement this, they instead give you a box to choose a repel.
Known issue: You can keep moving while continue use new one, a little worse than FireRed one.
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, Mesen, and MyBoy works fine.

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

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.

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.

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.

Battle don't divide EXP, including Exp. Share.

About this one, it seems to still share the Exp if I equip five Mons with Exp Share, albeit much less without the patch I think. I've experimented by equipping and removing Exp Share on two to more Mons

Here is another small patch: No EXP patch.

On other websites I only found large No EXP patches which were incompatible with romhacks, so I made this small patch which should be compatible with most binary hacks similarly to the rest of the patches in this thread. Only one hex value is changed to skip all stages of the exp calculation formula.
