The list could be expanded with the information that all SB16s have problem with SB Pro compatibility. With normal SB16s playing sound in mono, but Vibra chips playing stereo but in reverse. Don't know if the AWE64 plays in stereo too.

So SB16 Vibra models like CT2800/2900 /4180 etc will play SB Pro games that have stereo in stereo instead of mono.
First time i've heard that/. If this has been tested what game was used that supported SB Pro but not SB16 and had stereo digital sounds.

My CT 4520 AWE 64 value plays mono in SB pro mode, but when using the Midito utility that user aitotat wrote it plays stereo in reverse.
