Oh, thanks for the link. BTW what does PRG Maker Only means? Picture is picture, isn't it?
Hi there the content of the pack actually can be used in any engine. There used to be a 4 directional sprite sheet that was an edit of the RPGmaker base sprites but I removed them long ago and replaced them with my original 8 Directional ones. There's no restrictions on engines now. They are simply formatted for RPG Maker.
