James Surine has released Beta5 of his great Mame for Dreamcast emulator Mamed,here is what it says on his site:

MAMED beta 5 is ready and available on the downloads page. This is an update to yesterday’s release, it fixes two things. The sound drivers should be working in all games now, even if some of them sound realy sloooow. Second, since the mame core slows down a lot for certain games when it’s given several joysticks, I have removed the separate joystick support. All joystick stuff maps again to the keyboard, four joysticks are supported, just not as joysticks as far as the mame core is concerned. So the button mapping has changed yet again, sorry for any trouble.
