Sync game to an old VGA monitor which ran at 60Hz and things came out almost perfect. I just released version 2.11 which has a new command line switch -R. This syncs the game to the sound stream which makes games that use the pitfall style sound basically perfect. Like quadrun and some of the more recent demos. In other words, we should be putting out a pretty much exact match to a console's sound stream and then we let video follow the sound. Timing seems much better this way. I'm not sure why we don't make it default. Maybe later. We also made some adjustments to polynomials to match up better with things Adam Wozniak has been doing. I'd be interested to know if this makes things perceptibly better. As usual, thanks to Eckhard for doing much of this work. So did you get a new computer too Thomas? Can we write the next version of the emulator in Perl? ;-) John ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
