@Aerosys I noticed and fixed a minor offset issue. All characters appeared to have been shifted to the left by maybe 2 or 4 pixels. Is that the issue you were referring to?
To answer your question about target: MZ. You can safely use it on plugins that are compatible with MV AND MZ. MV doesn't support this feature, so there are no side effects at all. I use it for my plugins, too.
I cannot find a good documentation about this one, I'm afraid. But I can show you how I'm doing it.
