The compatibility list seems all over the place?
There's games on the list that are listed as 'Ingame+' that seem to work flawlessly, such as Toukiden Kiwami. Amd then there's ones in that same vein that are completely unplayable, such as Ragnarok Odyssey Ace, as the whole screen is green with outlines of the menus and characters.
You then have things that are in the 'Playable' list which are fine, like Odin Sphere, Shinobido. And then other things in that same 'playable' list like Soul Sacrifice Delta and Wipeout which are entirely unplayable with either heavy, constant screen flickering (Wipeout) or incredibly messed up graphics in (SSD) where everything looks like it's exploded.
