Notes

main PCB is marked: "assa 811" and "PL-01" on component side
ROMs PCB is marked: "PL-02" on component side
main PCB is labelled: "N.208" on component side
partially working

label format is:
------------
| 09 - 811 | -> ROM number - game number
------------

The background music is "Greensleeves" (google it). The only difference I can see from a "normal" Phoenix PCB is the MN6221AB instead of the MN6221AA.
Same music as Phoenix (Amstar, different music)
