- Add support for HD647180 (Z180) sound CPUs (once their internal ROMS are dumped). These are: Fire Shark/Same! Same! Same! Vimana


- Driver by Darren Olafson. Technical info: Carl-Henrik Skarstedt & Magnus Danielsson. Driver updates: Quench. Video updates: SUZ

- Fire Shark and Same! Same! Same! have a hidden function for the service input. When invulnerability is enabled, pressing the service input makes the screen scroll faster.

- OutZone (set 2) has a bug in the 68K code. An Jump instruction at $3E6 goes to to an invalid instruction at $13DA4. It should really jump to $13DAA. This bad jump is executed by flicking the 'Service DSW' while after the game has booted. The other Outzone set correctly goes to service mode, but this set just loses the plot.

- OutZone (set 2) uses different enemies in some stages and has extra bonuses compared to set 1. The music sequences are also in different orders between the sets. So which is the newest version ?

- Demonwld (Toaplan copyright) is a newer version, and has a different game level sequence compared to the Taito licensed version.
