    • Finally, multi System 16B (Sega)

      Something I've started to work on only recently but done a lot of progress.

      29 official games known on this system:
      - Ace Attacker
      - Alien Syndrome
      - Altered Beast / Jyuohki
      - Aurail
      - Bay Route
      - Bullet
      - Cotton
      - Dunk Shot
      - Dynamite Dux
      - E-Swat
      - Excite League
      - Flash Point
      - Golden Axe
      - Heavyweight Champ
      - M.V.P.
      - Passing Shot
      - Riot City
      - Ryu Kyu
      - SDI
      - Shinobi
      - Sonic Boom
      - Sukeban Jansi Ryuko
      - Super League
      - Tetris
      - Time Scanner
      - Toryumon
      - Tough Turf
      - Wonderboy III Monster Lair
      - Wrestle War

      Some games are protected with an encrypted 68000 CPU, others with an i8751 MCU, some with no protection at all.

      4 different romboards known:
      - 171-5521
      - 171-5704 (identical to 171-5521 but with different jumper settings)
      - 171-5358
      - 171-5797
      I've been able to reproduce the 171-5358 (no custom chip, no banking) and 171-5521/171-5704 (tile banking made with a PLD and few TTL chips).
      The 171-5797 contains a QFP custom chip so I put it aside from now.

      By choosing the appropriate romsets all games except Torymon can be played on the same custom designed romboard.
      At the moment I have 2 prototypes:
      - one for 171/5521/171-5704 based games
      - one for 171-5358 based games
      But with some more logic I think the 2 types can be combined (with a hardware banking enabling/disabling function). I haven't looked at a software solution yet so this could also be a solution (some games were launched on more than one romboard type).

      Given the fact my multi M72 testing is on hold this project might progress faster than expected.

      Also I still have to:
      - fully test the decrypted sets for Dunk Shot, Sukeban Jansi Ryuko, Super League
      - patch Tough Turf to bypass the i8751 MCU
      - find a way to run Toryumon on a different romboard than 171-5797 (probably not the most desired game in the list but I'd like to tackle it for the sake of completeness)

      First prototype in action:

      Yes can confirm this is 100% possible :D
      Which one? Hardware or software solution? Hardware solution I'm sure it will work.

      I love you and want to have your babies!

      In less creepy wording, count me in as interested. Have always wanted a System 16 multi.

      Happy to help in any way if needed. Keep up the great work!


      This! But with the completely creepy wording intact - I'm 100% in for one of these

      You're too late mate, I already chose a partner who has no balls and I'm not looking for change ;)
