Progress Report:
PSP, works perfect even loaded on Micro SD Card (Ys Seven, DXC)
Halo 1, Perfect.
Ys Celceta, plays well... plenty of slowdown.
Doom 1+2, LOL.
Ys games are perfect, even better with 720p, high pixel density (it looks more detailed)
Sonic Adventure, Great, some frame-dips, but still fully playable.
RE:Revelations, Same as SADX, still good.
Shovel Knight, Perfect.
Hyper Light Drifter, Perfect at 60fps.
Castlevania CoD, Too bad, unless I find some miracle speed-ups, it's a no-go.
Castlevania LoI, not yet tested.
Castlevania MoF, Perfect at Vita resolution.
Turok 1+2, Yep. Perfection.
I'll be tackling GC/Wii-ware soon enough, probably gonna transfer a movie on there just because.
Still waiting on my USB 3.0 for more storage (and desktop to GPD Win tranfers), Then I'll be taking on a beast... PSO2.
All in all, this thing is pretty fucking sturdy, the Sticks are a little on the sensitive side, Catches Wifi further than my phone, feels good.
