Does it matter which way to go? I just found out about this through the latest version of Make magazine which talks about PiPlay. I have an RPi2 with PiPlay on it now. Both use advmame 0.106 so it really wouldn't matter in terms of game support, correct?
I really like the web upload interface with PiPlay, makes it much easier to get the roms onto the system.
So far all the games I normally play it can handle. However, some issues.
I have to setup the controls for each game, global controls don't take.
For many game the auto resolution doesn't work well so I have to manually set it.
1944 not working. Though the rom I have is for 0.92 and up, but advmame is complaining about missing nffux.03. That's for the earlier version of the rom. I tried renaming the one file to that (nffu.03) no go.
Coin/start with an xbox controller doesn't always work for some reason.
