Yes, it works fine in 9.4.
Does it have online features tho? Still haven't played so Idk. lol
Sure it does, it works just as a regular ROM would but its way much smaller in size compared to a ROM. The scale goes sometimes beyond 100% in size. The only real downside is that they get installed really slow.
I mean it took me like maybe 15-20 minutes to install that .cia release of MM which works great BTW
