And it's pretty sweet.
Originally I just wanted a media player that can play my Gintama episodes without hassle - they've been encoded in *.mkv and caused quite a problem on my Raspberry Pi.
Since that thing came with a controller I figured I might as well use it as my new emulation machine and it works fairly well.
I was hoping that GC/Wii emulation would be a bit further ahead than it currently is because in China, the Shield has an "official" Nintendo emulator available and, as you'd expect, people already dumped it. But I do hope that it will move forward a bit more, Simpsons Hit & Run runs especially choppy (while Mario sunshine runs pretty smooth at 720p). And speaking of Sunshine, that game looks pretty neat even in it's natural resolution.
Dreamcast emulation is still surprisingly messy. Some games look fine, others look like a total mess (like Gut's Rage) while other games won't run at all.
PSX emulation is also a bit weird. While Dolphin lets me use individual settings for each game, ePSXe doesn't. So while a 3D game might look pretty great, a 2D game like Doom or Castlevania will look godawful with graphical errors all over the place.
I originally just wanted to stick to RetroArch - all stuff under one GUI but unfortunately, RetroArch is a bit cumbersome when it comes to organizing and managing ROMs. Or at least it looks like that to me. When it comes to PSX, it refuses to acknowledge PBP files or when scanning for PC Engine games, it refuses to acknowledge CD games. It's a bit of a shame, really because I really did like the whole Emulationstation/RetroArch combo on the Pi.
