WIP:
- 0.143u8: Added 'Unused' dipswitch.
- 0.113u3: Nicola Salmoria added proper MC8123 decryption code and MC-8123B 317-0042.key to 'Opa Opa' - Game now playable. David Haywood replaced old Sega System E driver with new one based on HazeMD. Changed description to 'Opa Opa (MC-8123, 317-0042)'. Changed clock speed of the 2x SN76496 to 3579540 Hz. Added dipswitches 'Coin A/B', 'Demo Sounds', 'Lives', 'Bonus Live', 'Difficulty' and 'Unused'.
- 15th March 2007: David Haywood - Nicola found a weakness in the way Sega generated their keys for the M8123 which made decrypting Fantasy Zone 2 and Opa Opa much easier than anybody had expected. Both games (running on the System E arcade platform) work fine with the SMS emulation from HazeMD. I need to port this over to MAME so that they work properly in MAME too. Aaron should be thanked too for noticing that the FD1094 keys were generated by a Psuedo-Random number generator rather than actually being Random, this was also found to apply to the MC8123 and was the basis of Nicola's work.
- 14th March 2007: R. Belmont - Nicola has fully cracked the Sega MC8123 encrypted CPU. This means, among other things, that games like Opa Opa and Fantasy Zone 2 now run. MAMEdev was afraid those games might be lost forever, since no working examples were known, but now they'll be back to life.
- 0.101u2: Changed region user1 to cpu1.
- 0.74u2: Added Opa Opa (Sega 1987).
- 0.37b16: David Haywood added Opa Opa (Testdriver). TODO: Game is decrypted, looks tricky.
