There's very little on the player module board other than the VS1003 IC. The VLSI chips are really easy to use if you can source them. It shouldn't take long for spidi to integrate the VLSI chip onto the clock port CPLD SPI controller board. How to get the audio out of the Amiga is the remaining issue, either a headphone jack through a hole in the case or some kind of connection into the existing Amiga audio out circuits. The software is looking ok already.
