Scion Seibu Denshi bootleg

This romset comes from a bootleg pcb.Game differences are none.

Hardware info:
main cpu Z80
sound cpu Z80
sound ics AY-3-8910 x2
Osc: 18,432 Mhz

Note 1:The main cpu is located on a small daughterboard connected to the cpu board,with some standard TTL ics,a 2732 rom (dumped) and a 6306 bipolar prom that i cannot.
Note 2:The background audio noise is present here,too.So i confirm that  bug.
Note 3:On the video board there is another bipolar prom 6349 (cannot dump yet),so that's why color emulation is imperfect.

All other eproms apart dumped are the same of existing set.
All eproms are 2764
