Question

[hee]

IIRC, character tables cannot exceed 255 elements because it is saved as a single byte in ROM. It's probably very difficult to change this so I won't even bother.

In Fire Emblem 7, which characters are "expendable" as far as modifying them goes? If I need extra characters to change, I doubt that changing things like "Wall" are going to work, and the large list of different generic units scare me.

I prefer not to change playable characters if possible.

Also, I was intending on adding alternate promotion items as well as a Sword of Seals to the game, and I'm assuming that these special effects (promotion, +30 hp on use, etc.) I notice the promotion folder, and I think I can figure it out, but just in case - how does one change/add to the Staff/Use Effect menu? That also frightens me because it claims to be partially hardcoded.

TL;DR

Which characters can I edit w/o bricking things and how to make custom staff/use effects

pretty much everyone can be edited without glitching except Wall and Dragon iirc

and assembly, lots of assembly

if you're making a hack from scratch, don't be deterred by generic enemy units, you have full control over what spawns and what doesn't; just follow the original game's example, perhaps renaming certain generics for certain chapter usage
