I own both mv and mz but a lot of the plugins I need to use only support mv so I was wondering if these would work in mv? I know most of the visustella stuff is ported yanfly stuff so it sounds like it would work on paper but I figured i'd ask you first.

They're not intended to be used for MV since some of them use newer functions from MZ that aren't backwards compatible, sadly. I have tested some of them such as the Gambling System which can be used in MV, but I'd advise against using them in anything but MZ since they haven't been tested thoroughly.
