CURENT PRICING: $275 with eproms/ $245 with no eproms




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

30 official games known on this system:
- Ace Attacker
- Action Fighter
- 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

Plus 2 "exclusivities":
- Bloxeed (extracted from a PS2 compilation)
- Fantasy Zone (extracted from a PS2 compilation)

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:



Extra info about multi kit versions:

V1 = games (not included, users have to find files on their own) stored in EPROMs, one version of each of the 30 official S16B games supported plus 2 additional games extracted from a PS2 compilation developed/ported for a S16B emulator (32 different games in total)

V2 = games stored on SD card, keys restore (with compatibility restrictions depending of the FD module you have, keys can only be restored for the module they were intended to be programmed to), supports all romsets except those with a MCU or encrypted sound CPU

V1 is ready for production, we're just waiting for made to order connectors to be manufactured.
V2 has no release date yet, prototype is far from final, although all functionalities have been tested and validated.

=> plus Bloxeed and Fantasy Zone

I should be able to test if an encrypted module can run as a standard CPU by writing its entire RAM with 0x40 as suggested by Eduardo.
=> Not working... For now?
So far best compatibility is FD1094 (20 different games over 32).


Please remember all kits come with blank EPROMs. Games are NOT included.
Fortunately for you I've developed a tool to help you build ready to burn files from romsets you would have got on your own:

http://www.filedropper.com/s16bromgen

Your programmer must support 27C322 (DIP42) and 27C080/27C801 (DIP32) devices.
Detailed instructions are included in the zip file.

How to install:


1) Remove OG romboard:

2) Install new romboard (pic to be updated with the current multi romboard version)

3a) If your board was equipped with a custom FD1089 or FD1094 main CPU module swap it for a normal 68000 CPU (10Mhz)

3b) If your board was equipped with a custom MC8123 sound CPU module swap it for a normal Z80A CPU. Sega has installed a Z80A (4Mhz) on the S16B motherboards where sound CPU runs @ 5Mhz, probably the extra 1Mhz was considered acceptable for the CPU. You can go for a Z80B (6MHz) if you're scared.

3c) If your board was equipped with a protection MCU (i8751) pull it

Is this kit still being made? If so, where do I express an interest to buy one?

Thanks!
 
Thanks! Which version will it be? I haven't been on A-P in a while, and am not aware of any new developments. Please add me to the list.
 
Hi guys,

Don't know if here is the right place, so if it's not please guide me to the correct place.

Well, after about 6 months, i've fired up my multi16 and got a black screen or sometimes a blue/purple garbled screen. I checked all the eproms and it's ok, checked the mainboard and works fine with my Altered Beast romboard, so i don't know where to start to try fix it, maybe the 74LS257, or GAL ?

Can someone help?

Thanks in advanced

So not one game is booting?
Sorry the delay in aswer you.

Yes no one game works anymore.

I've played a lot of time last year, so back it in the closet.....some weeks ago picket it up to play again and does not work anymore.

Cheers

Hello,

I am having an issue with a Rev 1.5 version of the multi. Overall, things look to work when I install it on a 16B motherboard. But, there is no sound, on any of the games, including the game serving as the donor, Shinobi. The OG Shinobi ROM board plays sound fine. No matter where I adjust the volume level to, there is no sound with the Multi. The Z80 is not an encrypted version, nor is the 68000 main CPU. There is no suicide battery nor an Intel security chip on the board.

What am I missing here?
 
Hello everyone!
Mitsurugi-w I would also love to get one. Could you add me to the list still?

Thank you!
