Thanks for keeping the site running as long as you have. And thanks for the mirror, I've been meaning to download the screenshots libraries for a while now.
MacMAME.net will be missed, but I'm glad MAME is still alive and well on the Mac and work is still progressing on MAME itself. The work done on it is still awe inspiring to me.
I've been reading your Atari Blog for a while now. Love some of the stuff you've been working on. I recently got an 800XL myself which I've been playing around with.
EDIT: Heh, 500th post. Good thread to do it in.
