Okay my RG-350 has arrived, what a beauty! I love it already, though I didn't get much time.
I did try XMAME v2.0 and can confirm that so far it's working very nicely.
I'm just going to tweak a few things over the next couple days and then will release something.
can you give us an update on Xmame 2.0? That would be awesome! Thanks in advance!
