Yes, we would like to provide you with a carbonized version very much. Question is when we will have the time to look into this. MacOS 9.1 now allows you to assign function keys. Be sure you are not putting the function keys under OS control. Sound is jerky under MacOS X Classic.
Sound emulation is very, very timing sensitive.
The result is that for an attention-seeking dog like Bernie MacOS X doesn't really provide the punch that is needed for smooth sound emulation. It's not an issue of overall system performance but distribution of available system resources. None of today's products support 800kB disks which is what you probably need. External USB drives can only read 720kB and 1.4Mb disks. 800kB disks use a different encoding.
