Cycle Maabou (c) 1984 Taito Corporation / Seta
Sky Destroyer (c) 1985 Taito Corporation
appears to be in the exact middle between the gsword / josvolly HW and the ppking / gladiator HW
driver by Angelo Salese
TODO:
- separate driver into 2 classes;
- reduce tagmap lookups;
- low-level emulation of inputs/soundlatch (controlled by several i8741, like Gladiator / Ougon no Shiro);
- color prom resistor network is guessed, cyclemb yellows are more reddish on pcb video and photos;
BTANB verified on pcb: cyclemb standing cones are reddish-yellow/black instead of red/white
