Sun and Moon introduced a feature where Pokémon can learn one or more moves when evolving, regardless of what level it evolves on. For example, Vaporeon will learn Water Gun when it evolves, regardless of whether it evolves on level 1 or level 100, or anywhere in between.
This brings that to Fire Red.
See here for the prequisites and help in installing them.
Open your terminal to whatever folder you want to download this repo into. Then, do the following to download the repo and build the included tools:
$ git clone https://github.com/Zeturic/bpre-evolution-moves.git
$ cd bpre-evolution-movesCopy your ROM to this directory and rename it rom.gba.
Open config.mk in a text editor to set some compile-time configuration.
The build system is smart enough to find enough free space on its own, but if you want it to be inserted at a particular address, you can specify it by updating the definition of START_AT.
If the given address is acceptable (i.e. is word-aligned and has enough bytes of free space), it will be inserted there. Otherwise, it will just use START_AT to determine where in the ROM it should start looking for free space.
If you are using Jambo's learnset hack to allow for moves above 511 to be used in level-up learnsets, set USE_JAMBO_LEARNSET_HACK to 1; otherwise, keep it at 0.
If you wanted, for example, Blastoise to learn Hydro Cannon upon evolving, you would add Hydro Cannon to the beginning of Blastoise's level up moves as a level 0 move. That's it.
PGE doesn't let you set a move to level 0 unless you are using Jambo-style learnsets. G3T lets you set a move to level 0, but doesn't support Jambo-style learnsets at all.
In short, if you're using regular-style learnsets, add your evolution moves using G3T. If you're using Jambo-syle learnsets, add your evolution moves using PGE.
