* Wanted: 317-0072 FD1094 CPU
WIP:
- 0.181: Sound improvements for clone Passing Shot (4 Players) (bootleg). Hook up MSM5205 and 74LS157, game now have some imperfect samples playback [ARJ].
- 0.175: Osso added preliminary sound to clone Passing Shot (4 Players) (bootleg).
- 0.166: David Haywood added clone 'Passing Shot (Japan, 4 Players) (bootleg of FD1094 317-0070 set)', 'Passing Shot (World, 4 Players) (bootleg of FD1094 317-0074 set)' and 'Passing Shot (World, 2 Players) (bootleg of FD1094 317-0080 set)'.
- 0.154: Alan Meades and Porch added clone Center Court (World, 4 Players, prototype, MC-8123B). Added MC-8123 key to Center Court [Charles MacDonald]. Added some additional notes about the Center Court PCB as well as change "BIN" to actual romboard PCB locations and a comment about the Center Court cocktail unit with full artwork [Brian Troha]. Added notes on Center Court bugs that occur on real hardware [David Haywood].
- 21st July 2014: Charles MacDonald - I've updated the FD1089 key management tool to support a brute-force LCG seed search function for the MC8123. This was used to produce a key for Sega's Center Court that was recently dumped and added to MAME. Some plaintext must be provided to carry out the search. It only took 8 bytes of data from Passing Shot to make a match, in this case the code for the NMI handler that sends ADPCM data to the uPD7759 was used as it was the least likely to be altered in Center Court. The tool supports searching for plaintext within a range of addresses so that matches can be made if the encrypted code or data is a different location than expected.
- 17th July 2014: David Haywood - A few weeks ago I did an update about Ken Sei Mogura, a rare Street Fighter II themed Whac-a-mole game found by Alan Meades at a disused location in the UK. It turns out that was not the only rare game being stored at that location. Also there was a very dusty looking cocktail cabinet marked 'Center Court' with full original Sega artwork etc. We knew from Japanese flyers and a review in a UK magazine that Center Court was an alt title for Passing Shot, but apart from those references and the odd photo of a cabinet there had been no trace of it. Alan returned to the site and picked up the board (with a view to fixing it / restoring it for actual use) and it quickly became apparent that this was a bit more than a simple clone; to cut the story short it's a prototype. A picture of the board can be seen below. Immediately obvious are the handwritten labels, while the game does have official Sega EPR stickers the numbers were not finalized at this point so instead the locations have been written in, and for the program roms the checksums of the current build. The other important feature to note is the use of the MC-8123B. The MC-8123B is an encrypted Z80, all other versions of Passing Shot use a regular Z80 and an encrypted 68000 (Fd1094) instead. This has the 68k unencrypted. The game also has 8 sprite roms whereas the final version uses 6. The board was sent to Porchy and he dumped the roms remarking that the legs on them were in a very fragile state and, despite the clean appearance of the boards in the photo, it seems this is another to file under "saved just in time". Anyway, looking at the dumps I could see that aside from the sound sample roms they all differed when compared to the other sets. This suggests that the sound code / samples were probably final at this point, maybe why Sega chose to encrypt the sound program. Charles MacDonald has a tool to help decrypt the sound programs, but for the time being I opted to load the original sound program rom over the encrypted one on the gut feeling that once decrypted the code will be the same. Upon booting the games in MAME a number of differences were immediately obvious. I've put Center Court screenshots on the left and Passing Shot screenshots on the right. There could be other differences too, but those were the most obvious once. The first time I booted Center Court I was surprised by something else too, debug text on the screen. After playing with the dipswitches a bit I found that the 'Demo Sound' dipswitch turns On/Off this display instead of turning On/Off the Demo Sounds, again further evidence for this being a prototype build. Another very nice find, huge thanks to all involved!
