I tried Abyss and Keen on real stock A1200.
Link to abyss data gives me 403:forbidden but I found it on similar site.
Keen is fully playable.
Abyss still not quiet. I'll upload you video to see. And loading times are reeaaally long.
Would it be possible that you change the pallette?
Here's the video:
