I just checked in to start off the obligatory "MacMAME on iPhone" topic... but this topic seems much cooler.
I'd love to take this opportunity to thank Brad for all of his work on MacMAME. It opened my eyes to the world of emulation and filled my nostalgic arcade jones time and time again. Thank you.
And congrats on working for the "mothership". I think we all have that desire to a certain degree, but few of us get to realize it. Good luck.
