I had my friend ask about the G1. He told me that the people were very busy, and kind of uptight.
They crammed a flyer in his hand for the upcoming PC version of the G1.
It mentions nothing of MAME. He said he asked about MAME, and the person didn't have specifics. So, in the end, all I know is that the PC version of the G1 will be released sometime later this year.
I wish I would have been there to ask. I wouldn't have let them off so easily with the weak answers.
