This is my first post here, so please be kind, and it's been quite some time since I worked with my real CoCo (which is a dragon clone, as I'm sure you well know). Ciaran mentioned that I should come here, in case someone was interested in the PS3 port I completed.

The sound libraries on the PS3 are still in their infancy-- so sound emulation is not the best.
Here is the official release thread, but I will try to answer PS3 related questions here, since I'm sure you all will not have the same questions they would have in that thread.
Below is a screenshot from the PS3 implementation:
