Notes
Most of the time the main SEGA IC's are based on/renamed chips from other brands as follows:
- MD1 VA0, VA1, VA2, VA3, VA4, VA5, VA6, VA6.8
- Yamaha YM7101 / FC1001 = Sega 315-5313 / 315-5313A / 315-5313A-01
- MD1 VA7 & MD2 VA0, VA1, VA1.8, VA3
- Yamaha FC1004 = Sega 315-5487 / 315-5487-01 / 315-5487-10 / 315-5660 / 315-5660-02 / 315-5708 / 315-5708-01
- Sega Nomad & some MD2 VA3's
- Yamaha FF1004 = Sega 315-5700
- MD2 VA2, VA2.3
- Toshiba T9N13BF = Sega 315-5786
- Toshiba TC6158AF = ???
- MD2 VA4 & GEN3 VA1
- Yamaha FJ3002 = Sega 315-5960
- GEN3 VA2
- Yamaha FQ8007 = Sega 315-6123
