Hi Telverin.
It is possible to rename the spell and change its visual effect into an already existing visual effect. The most straightforward way is to directly edit the modded files in AF's folder:
- for the visual, it's "AlternateFantasy/StreamingAssets/Data/Battle/Actions.csv",
- for the spell's name, it's "AlternateFantasy/FF9_Data/embeddedasset/text/us/ability/aa_name.mes" (replace "us" by another language if you don't play in US english).
These files can both be modified using a text editor. The CSV is a spreadsheet so it may also be edited with a good spreadsheet editor, but you must beware of keeping the exact same CSV format, which some spreadsheet editors can't do.
Another way to do that is to use the tool Hades Workshop. It takes longer to load but it gives a more comprehensible interface, so you don't have to figure out what number you need to input in spreadsheets. For that:
1) Download the tool
Hades Workshop.
2) In that tool, "File -> Open -> FF9_Launcher.exe" (in your game's directory), then "File -> Open Mod -> AlternateFantasy_v5.2.hws" (that file is provided in the download link, inside the "Source v5.2" folder), let every available option checked and proceed, then wait for the datas to load (it will take some time).
3) In the "Party -> Spells" panel, search for Free Energy. There should be 2 of them, the first is the non-trance and the second one is the trance version. Change the "Name" and "Animation" of these.
4) "File -> Save Steam Mod -> Raw assets + Spreadsheet" will generate a mod folder comparable to the "AlternateFantasy" mod folder.
5) Merge the folder you generated into the folder "AlternateFantasy":
--- the new files from your folder should replace the files from "AlternateFantasy"
--- but there are also files that are present in "AlternateFantasy" and not in your new folder and it is important for them to be in the result of the merging.
6) That should be good. In case you rename the folder that is the result of the merging (instead of keeping "AlternateFantasy"), you must register that new name in the Memoria.ini in place of "AlternateFantasy".
