movies: 20fps
menus: ~40fps
ingame: ~5 fps (but goes to 30fps with vu skipping)
tested on:
pcsx2 0.9.4
zerogs kosmos 0.96.4
linuzappz cdvd 0.7.0
an unreleased spu2 plugin
Game is extremely stable, all movies work without freezing, and sound is beautiful. I would call it playable if ingame 3d graphics weren't as slow and ZeroGS KOSMOS didn't consume my entire computer resources. If even there existed a fast enough processor (and I assure you, there doesn't), the wall outlet wouldn't be able to supply enough power to run the game in real time (this will be fixed by next official release). It should be noted here that ZeroGS was named after the character in this game due to this very reason.
This is the first dvd9 (dual layer) game to work for pcsx2. Coincidentally, it is also the first dvd9 game to be released on the ps2.
