Coliseum normal battle

That subroutine will cure all negative statuses, but it excludes MagiTek and Interceptor status because those statuses are intentionally set and not considered negative.

It can be done by event. The colosseum fight is at $CB78E9, if you put a hook (B2 command) at $CB7972, you can do your restore/remove HP/MP/status there. It will work for every colosseum fight except the Shadow one, which the after fight event is from $CB78F4 to $CB796B. However there is a branch to $CB7972 if you exit the item choosing menu ($CB78DD) so you might want to copy the $CB7972 code elsewhere and branch to that for this case to prevent HP/MP restore by simply entering and exiting the item betting menu. There might be a better way to do this, idk.

Ok. So I get that CACFBD remove all statues except those 2. And B2 cmd is the "Call Subroutine", so I will put CACFBD at $CB7972, right? However, the game screen does not return, so it remain black. 

But there was another objective I want to ask today. Where is the original healing code at the colosseum fight between $CB78F4 to $CB796B? The game clearly revive my KOed character, & max heal them (just not negative status), but where is that code within the colosseum codes? Is it $CB795C?

Edit: According to the FF Fandom on the coliseum. All statues should be removed except for Float, Poison, & Imp. But they didn't.
