[FE8] How to create a custom stat booster?

Hi. I’ve recently started hacking FE8. I’m using various tools such as FEGBABuilder, Nightmare and FEditor. Until now, I could handle myself, but I’m having some trouble with creating a custom stat booster item.

I managed to set up the text and the stat increases it gives (+7 HP, +2 Str, +2 Skl, +2 Spd, +2 Def, +2 Res, +2 Mov and +2 Con. Basically all stat boosters in one item), so I went to test it out, but it won’t let me use it.

I’m assuming this has to do with the “use effect” option, but I dunno what I have to insert there, exactly.

Any help would be appreciated. Thanks!

Since stat booster has part hard-coded in program code, I think it is difficult to add it.

It is easy to change the effect of existing stat booster,
But if you want to add them newly, I think you have to parse the program code.

You need to edit the usability tables. (Or, ideally, write a custom condition that checks for any one of those stats not being capped)

With the latest version of FEBuilderGBA (ver 20171214.21), you can now access item effect tables etc.
You can access it from “Item use effect” on the detail menu.
As you switch combo boxes, you can also access other tables that build stat booster.
