What is needed hex editor
1. Level Evolution
Example: Bulbasaur
[ 0400 ] [ 1000 ] [ 0200 ]
Meant: [ Level evolution = 0400 ] [ level = &H10 = DEC 16 ] [ Evolves into Ivysaur = 0200 ]
2. Item Evolution
Example: Gloom
[ 0700 ] [ 6200 ] [ 2D00 ]
Meant: [ Item Evolution = 0700 ] [ Item = 6200 = Leaf Stone ] [ Evolves into Vileplume = 2D00 ]
3. Trading Evolution
A) Example: Kadabra
[ 0500 ] [ 0000 ] [ 4100 ]
[ 0500 ]=Trading Evolution
[ 0000 ]=It always works.
[ 4100 ]=Evolves into Alakazam
B) Item-based Trading Evolution
Example: Porygon
[ 0600 ] [ DA00 ] [ E900 ]
[ 0600]=Item-based Trading Evolution
[ DA00]=Item, which is Upgrade
[ E900]=Evolves into Porygon2
4. Friendly Evolution
Example: Cleffa to Clefairy
[ 0100 ] [ 0000 ] [ 2300 ]
Meant: [ Friendly Evolution = 0100 ] [ 0000 Evolves at maximum friendliness when it levels up ] [ evolution to Clefairy = 2300 ]
5. Stat-based Evolution
5a)
Example: Tyrogue to Hitmonlee
[ 0800 ] [ 1400 ] [ 6A00 ]
[ 0800 = Attack is higher than Defense ]
[ 1400 = Evolves at level 20 ]
[ 6A00 = Evolves into Hitmonlee ]
5b)
Example: Tyrogue to Hitmontop
[ 0900 ] [ 1400 ] [ ED00 ]
[ 0900 = Attack equals Defense ]
[ 1400 = Evolves at level 20 ]
[ ED00 = Evolves into Hitmontop ]
5c)
Example: Tyrogue to Hitmonchan
[ 0A00 ] [ 1400 ] [ 6B00 ]
[ 0A00 = Attack is lower than Defense ]
[ 1400 = Evolves at level 20 ]
[ 6B00 = Evolves into Hitmonchan ]
6. Time-based Friendliness Evolution
6a) Daytime Friendliness Evolution
Example: Eevee to Espeon
[ 0200 ] [ 0000 ] [ C400 ]
[ 0200 =Evolves during the daytime at maximum friendliness (when it levels up) ]
[ 0000 =?? ]
[ C400 = Evolves into Espeon ]
6b) Nighttime Friendliness Evolution
Example: Eevee to Umbreon
[ 0300 ] [ 0000 ] [ C500 ]
[ 0300 = during the nighttime at maximum friendliness (when it levels up) ]
[ 0000 = ?? ]
[ C500 = Evolves into Umbreon]
After the evolution data there are 40 bytes that all say %uFFFD00%uFFFD.
Every Pok%uFFFDmon has up to five spaces for evolutions.

Also, go to the tools section, in the temporary tools resource. They should have a link to "Whack a Hack". That site, if you look around the menues in the top section of menues in the sidebar, there should be one with hex numbers for Pokemon and items.
