I can confirm the current trainer works for the Steam version. Playing it right now, in fact. The INF HP & MP codes only work for the slot 1 character, like before. And the Add Gil option works after you fight your first battle. Same for the Add Experience. Does not keep you from getting Achievements.

I mean if it only works for slot 1, then I guess it's ok.
I was debating whether or not I should get it and was wondering if anyone had trouble using the trainer with the Steam version.
Does the add EXP work with every character or just slot 1?
