I have about 670 titles according to Proton. So far the ones that don't work are:
The Typing of the Dead: Overkill,
Darksiders,
Duke Nukem Forever,
Universe Sandbox Legacy,
Aliens: Colonial Marines,
Agents of Mayhem,
Dark Void,
Splinter Cell: Conviction,
Chime,
Homefront,
Dead Pixels,
Kyn,
Shock Troopers,
Twinkle Star Sprites,
Viking: Battle for Asgard,
The Last Blade,
Shock Troopers 2nd Squad,
Kill la Kill -IF,
DJMAX Respect V,
Destiny 2,
Scavengers,
Dirt 3,
Driver San Francisco,
Darksiders II,
Transformers: Fall of Cybertron,
DisplayFusion,
Star Trek,
Deadpool,
Adventure Time: Explore the Dungeon,
Amazing Spider-Man 2,
Spider-Man: Shattered Dimensions,
& Wallpaper Engine.
The only one that MAJORLY bums me out of DJMAX. I was really looking forward to a portable version of that. But at least Groove Coaster is Platinum.
