Obviously I didn't saw this : - 0.145u7: hap added sound to Rabbit. Added I5000 (40MHz) sound. ...Now I am a little bit confused; is Imagetek I5000 video or sound chip or both ? Anyway You (MAME devs) needed almost 8 years(!) from this : - 17th July 2004: David Haywood made some progress with the Rabbit driver and R. Belmont included some preliminary notes about its sound in the driver. ...to this : - 0.145u7: hap added sound to Rabbit. Added I5000 (40MHz) sound. All I can say is Thank You for Your work and Your enthusiasm. P.S. I can hardly wait for 0.147 to play all those kinky games with QS1000 sound !
