Good idea. Looking at current git, using ym2203 and z80 as filter criteria narrows it down to 99 drivers; within those, these are the 78 games that load exactly ten rom files: Spoiler Code: bigbang blkheart blkheartj bygone chrygld cmasterc deadconx deadconxj drgpunch euroch92 extrmatn extrmatnj extrmatnu extrmatnur flytiger fm7740sx footchmp gaia gakupara grmatch growl growla growlu gtg2 gtg2j gtg2t gunfront gunfrontj hjingi hjingia hotdogst hthero hvyunitu macross macross2 macross2g megablstj megablstu metalb metalbj mjclinic mjhokite mrokumei ncb3 ninclown ninjak ninjakj ninjaku pass pc8801fa pc8801mh pc8801mk2mr pc8801mk2sr pc9801bx2 popbingo powerinsa psychic5 psychic5j pulirula pulirulaj quizhq qzchikyu qzkklogy raiga rambo3 rambo3u rimrockn runark stg stratof tdragon tdragon1 tdragon2 tdragon2a theroes tknight tnextspc tnextspcj Next step would be to look at the rom sizes, I guess, but honestly I'm too lazy for that, so if anyone wants to step in... Also, I only checked for "at least one" ym2203, not "exactly two", so that's another possible refinement.
Nice As it had a sticker "Player 1 Jump and Shoot" and "Player 2 Jump and Shoot" it could be something around Rambo 3 or Gunfront or...man I just realized I dont know many of those names. :/ I sent the board to Bad_Ad84 and it should arrive any day now.
Now I'm wondering what that jump button is for. (And why neither Exerizer nor Sky Fox are on the list of games I extracted from MAME. edit: Ah for some reason it loads more roms (13) than I expected. odd.)
So just another Zaxxon, Xenon clone Known as "Sky Fox" outside of Japan. So in japan it is called Exerizer...what did this game do in a german pub then ? ^^ I love the sound effects :'D !!! And it says bootleg on the link you gave. Hmmmm.... http://www.ebay.com/itm/PCB-EXERIZER-SPACE-PILOT-JAMMA-/171805386312 http://www.ukvac.com/forum/exerizer-pcb_topic339351.html If you think its worth putting it on ebay to make a fortune we can share 50:50, feel free to do so. Else just keep it, as I dont think its worth to spend another 15 € on shipping it back to me. Thank you for solving this mystery !
