Not really. Otaku Studios' owner got sued by sulake for licensing an emulator (phoenix) and making a shitload of money off it. There are still a lot of retros that get many users. A couple english ones are Fresh and Habboon. There are also some foreign hotels that get 1-8k daily as well. Most...
I don't know what "plus3" is. I'd recommend using AKIIX's edit. I'm pretty sure it doesn't have the disappearing furni bug. And the catalogue from Skybird Emu is pretty decent.
Habboon is using PlusEMU, but it's highly unlikely that you'll get your hands on an emulator like theirs. I'd use SwiftEMU myself, because it has the most features.
