Notes
Scion Seibu Denshi bootleg.
This romset comes from a bootleg pcb.
Game differences are none.
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 dump.
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.
