MamedDC tidbit

Some more news from the DC sk3n3’s leading newsposter,Wraggster, he relayed some info from the MamedDC forums that James Surine posted in response to a question about sound & Neo Geo speed improvements in the next version of MamedDC:

There have been some speed ups in KOS but sound is still a problem, read the recent interview with the guy working on the divx port, sound is still a problem. The main thing we need is a decent isr driven ping pong buffer sound driver. Currently everything is polled which slows down the main processor trying to keep the sound processor fueled with sound data. There have been some improvements with page flipping with TA frame buffers using isr’s and queues which should help some. That’s what the guy who posted the pacman screens was working on. Nothing solid yet for MAMED though but only time will tell.
