Super star wars is a direct port, not emulation. It's not a ps2 game.
I didn't mean to bump this thread up from the abyss.
Super Star Wars was just the one that was tried to make sure Share Play was working at the time. It's the one that should/did work because it was launched on the Playstation Store.
There's other PS2 games coming out tomorrow on PS4. Might need to revisit whether these Star Wars games will have Share Play enabled now that the PS2 Classics line has launched.
Totally random but I was scrolling through the thread and someone asked about background music. Spotify doesn't work. The music fades out when you go into a PS2 game. These things pretty much operate like PS4 native software with this exception. Cloud saves, broadcasting, DVR/screenshots, Remote Play, and Share Play.
