Just started messing around with mine. Got my PS3 controllers to work perfect with it. All the games load up nicely...those damn arcade ones, though. There's only a handful I really want quick access to, but figuring out which one works with which emulator sucks.
Good thing it saves it for you
There is lag just make sure your on the latest 8bitdo firmware and you have the controller plugged in to the pi as using bluetooth gives large amounts of input lag.
How do those zero's run? My guess would be most all the cart systems before n64 and about 85% of arcade stuff that doesn't need .chd files.
I do. Great for emulation of classic consoles. Not so great for arcade games as the MAME build it supports is straight up ancient (0.38 if I recall).
Its easy to configure basic controls, but a giant pain to use some of the more common emulation features such as graphics filters.
Double edged sword, but great for the cost.
There's about 20 versions of Mame and other arcade emulators it supports, I think 2014 plays the newest romset of 1.59 (mames @ 1.69?) It think its Mame4all that run near perfectly.
Here's what I did, think I already have a 1.59 set, then I downloaded a final burn .38 set. I deleted all the games from Mame that are also in 1.59. Took out the other system roms that arnn't arcade from final burn and put them in it's folder and put the left over ones in the mame folder. Then I start every game with the default emu and if it doesn't work , (usually does) then I start going down the line until it does. I'd say other than .chd games I have about a 95% success rate, and those are usually known broken, incorrect dumps. Next I need to take out those .chd games but I think i have another microcomputer
they may work on.
I also have a Odroid Xu3 with 64gb mmc, it has a (big little) two quad processors 2ghz and 1.5ghz making it an octocore with 2gb of ram.
So far I've only gotten it to multiboot with Andrio 7, Debian (Jessie), and Openelec (Kodi). Kodi run so much smoother on it than a pi. Even though its over 2x as power as the Pi3 it doesn't have near as much support making it not that much better.
I'm going to try and mainly use it for bigger and newer files/systems like N64, PSX, PSP, Dreamcast.
Theres a Xu4 out now and it's basically the same thing but only $75.
