Emerald: Adding New Evolution Methods

[anonyboy]

Spoiler:

Step 1 (Extending the table and limiters)

Spoiler:

First, fire up your ROM in a hex editor and navigate to 0x6D198. Select 0x3C bytes and copy them to some free space.
Next, we must change the pointers to our new location,Search 98D10608.
There is only one pointer at 0x6D194.

Next the game has a limit on the number of evolutions. This is at 0x6D180. Change this to the new number of evolutions (in hex)

Step 2 (Porting routines from FireRed to Emerald)

Spoiler:

Well,Since all methods existing for FireRed, We Don't need to make new ones for Emerald.
1. Here are some offsets needed for porting:
levelcheckloc: .word 0x0806D32F
noevo: .word 0x0806D333
decryptpoke: .word 0x0806A519
encryptpoke: .word 0x0806ACAD
firstpoke: .word 0x020244EC
mapbank: .word 0x020322E4
map: .word 0x0203732C
basestatstable: .word 0x083203CC (If you have expanded the number of pokemon in the game, change this to the Base Stats Table in your game)

2. Changing Offsets in routines:
Example:
Here is FR's Male Lvl Evolution:

noevo: .word 0x0806D333
decryptpoke: .word 0x0806A519
pokemondata: .word 0x083203CC

Step 3 (Making the routine work in the game)

Spoiler:

To make this compatible with G3HS open up the .ini file and navigate to these lines:

evolutionmethods =
evomethodsproperties =

Add in a name for your method, and for properties add either Level, Item, None, Move, Pokemon, Location
Note: Follow KK552's syntax for the ini file.
Finally open your ROM and in G3HS and work add the evolution and test it!!!

Final Notes

Spoiler:

If you have used the "Changed Number of Evolutions per MON'" button on G3HS, these routines ain't going to work.
Assemble them anyway and change the .bin file accordingly.

8 evolutions per mon: Change F0 19 to 70 00
16 evolutions per mon: Change F0 19 to B0 00
32 evolutions per mon: Change F0 19 to F0 00

oh ya ,it is beautiful.we can learn more from to

Do you have the ASM code for the Gender-based Dawn Stone evolution for Emerald? I have implemented Dawn Stone for my Emerald hack (example any free item index number) that will evolve a male Kirlia and a female Snorunt into Gallade and Froslass respectively.

The Code for dawn stone isn't inserted like normal evo methods... Pretty much only Gogo has a dawn stone code but it's for fire red and not public. Soory bro,

Btw, if anybody knows the offset that checks time in EM? I need it for time based evolutions.

But you could just create a new item as use that as an evolution stone. So really there is no secret code for doing so.
And just a theory but to creat a gender based evolution stone what you could do is take the base evolution stone asm copy it and edit it so it adds an additional check for the gender. Idk if it would work but still.:)

 

[LCCoolJ95]

I'm sorry about bumping this thread, but it has to be known. Okay, so checking this with expanded mons, even changing offsets to the new offsets (base stats and move data), I can confirm that the new evolution methods will NOT work.

 

[jirachiwishmaker]

I have had found out the currentweather ram of Emerald, so now has the new evolution method of Raining in the Overworld (Goodra) for Emerald.
