Currently, it implements the ATAPI READ SUB-CHANNEL command and fully supports the current position data format code. Other format codes like ISRC and UPC currently return dummy data, but wiring that up would be pretty straightforward. Supporting image formats like CloneCD's .ccd/.img/.sub that store arbitrary subchannel data also seems doable, but would definitely be more work.
