What is Ambience?
Ambience is basically a small MP3 player that runs in the system tray (written by ShanMan)... Pretty cool little utility. I kick it off with a bat file if that makes a difference:
startup_app_commandlines c:\ambience\startambience.bat
exit_app_commandlines c:\ambience\stopambience.bat
I'm running it from a bat file as this allows me to delay it's startup by 20 seconds so it allows my startup video to finish playing before it kicks in... and the other bat file kills it off when I quit Mamewah. It works for me - unless there is an easier way to have it delayed start and then quit with Mamewah.
I'll give 640x40 and hwstretech a shot and see how that works out. Should I just specify that in my mame.ini or switch my desktop, mamewah, and mame to all run 640x480? BTW, I'm running this all on a 21" Dell UltraScan P1110 monitor (Sony Trinitron).
