The author of MAMED (MAME for Digital Cameras) has updated his site with news of MAMED progressing on your beloved Dreamcast! This direct from the site:

Things are progressing, I have the code running now right up to just before emulation starts. It crashes right afterwards but the roms are loaded and everything is initialized. There is no input yet (keyboard or joystick) and the code is riddled with debugging code but hopefully those little pesky pacman ghosts will appear soon. Yes, I know the color is all screwed but who cares at this point anyways. Thanks for all the nice supportive e-mails, and as for all those nay say-ers on the boards….don’t bother downloading it when it’s done.
