PS2 emulation on PS4 incompatible with discs, Dark Cloud leaked

More information due at PlayStation Experience, we assume.

Dark Cloud will be one of the PS2 titles Sony Computer Entertainment brings to PlayStation 4 via PS2 Emulation, and said emulation won’t support PS2 Classics purchased on PlayStation 3 or PS2-formatted discs, a leaked video reveals.

Twitter user @BradazKing noticed the video, which the PlayStation account published and quickly removed, which features Dark Cloud gameplay on PlayStation 4 and the following description:

Gameplay footage from Dark Cloud PS2 game on the PS4 system. Experience Dark Cloud with 1080p up-rendering and Trophies. Additional enhanced features include Shareplay (Active PS Plus membership may be required), Remote Play, Activity Feeds, and Second Screen support for game manuals through the PS Vita system or PlayStation App.

The image above is a thumbnail from the YouTube video, grabbed via Boingboing.net. The video itself was not downloaded before its removal.

PlayStation Experience is this weekend, and Sony is expected to detail its plans about PS2 emulation at the opening keynote on December 5 at 10 a.m. PT.
