Retro Mac OS emulation

Hey guys, new to making posts here but would just like to pose a question.

Anyone familiar with some good OS 9 or older emulators? I've tried Mini V Mac but am not technically savvy enough to figure it out...something about installing a ROM and bla bla bla.

I grew up with these older machines and am trying to feed some nostalgia without getting too deep into the tech stuff. also windows 95 emulation would be cool too.

anyway I know this is such a niche thing that I probably won't get much of a response but even so please feel free to reminisce about early tech here. and if you know anything point me in the right direction.

thanks.
