What is cool about these versions is that they do have some audio capabilities, although they are so old that they do rely on sampled sounds for:
But it’s from 1999 and that was the state of emulation.
0.82 is basically where the project had left off, and was of course supplanted by MAME. There was preliminary work on AfterBurner 2, although there is from the looks of it a bad/partial ROM dump to blame for the most part. It’s unplayable but it sort of runs the demo.
0.82 does however emulate a strange version of OutRun. Namely that it lacks shifter support all together. So hold down the accelerator and take off!
Notable things is the inclusion of Neill Corlett’s Starscream for 68000 emulation, Neil Bradley’s Mz80, Jarek Burczynski’s YM2151. Which reflects many components of the era that would find their way into MAME.
Which of course speaks to another thing, that tracking down ROMs for these ancient pre-mame emulators is getting impossible with vague names, and no timestamps.
Btw, there is two excellent pages where you can get all the roms supported by this emulator, these pages are : http://www.davesclassics.com by Conjurer and http://www.emuviews.com by JoseQ
Which naturally, are lost to the mists of time.
I’ve been able to run it under DOSBox, Qemu and VMWare. For VMWare, be sure to enable Sound Blaster emulation, and set the BLASTER environment variable to:
SET BLASTER=A220 I5 D1 H7 P330 T6
The video mode for the start screen doesn’t render on VMWare or Qemu, so in that case I just start it with the following batch file
I don’t have the FPS stats as it’ll crash when going to the menu to exit, and I didn’t hack up the source that much at the moment (caught another flu…). But Qemu 0.90 feels a LOT more fluid playing outrun than VMWare or DOSBox on my 2006 Mac Pro. Although on my 32 core Xeon monster it plays great on everything. I guess if you have at least 3Ghz and your CPU is less than 8 years old it’ll be fine for running nested emulation along with emulating 2 68000’s a z80, and a ym2151. Or just run a native build of MAME! Or if you really want low lag Outrun, use Cannonball!
And thanks again to Thierry Lescot for letting me redistribute this
I saw these at a local Toys R Us, and picked a few up. They were selling for $200 HKD which is about $25 USD. They are SUPER tiny, and yet very cool to actually play with. They feature a single game on each cab, and luckily there is no coin slot, just a player 1 button. As a bonus the marque does light up, which is why I wanted to do a dark/night picture of the machine.
The games have been modified for what I’d assume is an ARM SOC, and game play is somewhat easier. For anyone looking for the exact arcade expedience, they will be no doubt disappointed as many things like sprite animations are simply lacking in this version.
That said the controls are surprisingly very responsive, and it’s almost a treat to play, except of course that the screen is so incredibly small, the sound is faint, and it’s not hard to have your thumb in the way obscuring things.
It’s a neat novelty item, but it’s no substitute for a nice USB arcade stick & a copy of MAME, or the actual PCB & a JAMMA harness.
So, Ive been playing around with emulators, and for some reason I think it’d be awesome to have a real one. So I check ebay, and yeah there is a few, Altered Beast, Shinobi, and even an Outrun, and a couple of Hang Ons! Wow this is so cool, then I check the prices, and shipping and yeah it’s REAL expensive, REAL quick. And even back when I did own an Altered Beast board, I never got it hooked up as it was ‘too hard’.
So, I’m about to give up on the whole thing, then I spot this Altered Beast board, for sale for a mere €50! And the shipping isn’t too insane either! But looking at the PCB board in the picture, and I can tell something is not quite right:
Now for those who don’t know, this clearly is not a System16 board. However it certainly does have a 68000, and z80 processor! Could this be some 2nd tier manufacturing job? Or perhaps it’s one of these infamous bootleg boards?
For comparison, here is a real SEGA System16 board
As you can see, they really look nothing alike. Also the other give away is that the far cheaper €50 board is JAMMA compatible. All the old SEGA boards are not.
What the heck is JAMMA anyways? You see that edge connector? That is where you would plug in the power, coin catchers, the player buttons, and the speakers to. Even in the old days, recycling cabinets was a thing, and having modular boards was a ‘good thing’. But SEGA didn’t want you to swap out their boards with anyone elses, so they used their own system. But it’s just a wiring thing, there is nothing digitial locked down, no encryption either (look at HDMI!). So you can use an adapter, to interface from SEGA to JAMMA.
Anyways, I went ahead and placed the order.
Now doing some more research, and the monitors used in 1980’s arcades were RGB+Sync driven. Which are ancient, and of course, HEAVY. But a little bit of searching led me to the to the GBS 8200 v4.0.
AKA known as the “GBS8200 CGA/EGA/YUV/RGB To VGA Arcade Game Video Converter”. Well this certainly looks perfect! I mean from the description alone, it’ll do what I want. Even better they make them a few KM from here, and I could get one for ~ $20 USD. Perfect.
Next up is the power, I decided to get a “JAMMA” power supply. A bunch of searching, and this one was the cheapest one I could find, and again shipping wasn’t too bad, but not great either. The supply was again around $20 USD, but shipping was $15. OUCH.
I figured having the ability to screw in would be a ‘good thing’.
Naturally, I need the cables to wire this mess together, so I ordered a “JAMMA Cabinet Wire Wiring Harness Loom” for about $15 USD. Naturally mine is all in Chinese since I went cheap. But it’s OK, I have a multi meter so I can test continuity.
Finally I saw a QANBA N1 arcade style joystick in a local mall for $230 HKD. That is less than HALF the price of the ones I see online in the USA, Europe, or Canada. So at least that is nice. Now with all the parts, I just have to wait for the board to arrive. And wait, and wait. Nothing updated on ebay, then suddenly I check a few days later, as it’s been two weeks by this point, and it turns out that it’s been sitting in the post office in Hong Kong for a week! If only they let me know… SF Express, and FedEx have come without issues. Oh well, now I have the board!
I can now finally flip it over to reveal:
It’s all 74L TTL logic chips, EEPROMS, and some PALs as well. There are NO custom SEGA chips at all. If anything this is what is inside of the SEGA ASIC’s on the System16 board. Whoa.
Ok, so this is certainly a bootleg board. A quick search of MAME shows that they have a Datsu ROMset, so maybe this is one? Nothing on the boards say Datsu, however it does say ALTER/S, and it shows being QA’d on 11/11/88.
Now it’s time to cable this thing up!
But first JAMMA boards are typically key’d so you cant put the adapter in backwards. There is no key on this board, so I need to check the voltages to make sure I don’t flip it backwards.

This is the standard pinnout of a JAMMA harness. Importantly you can see it’s Ground than +5v. So looking at the 68000 processor to check it’s pinnout:
You can see it’s power input is on pin 14. Likewise, the ground is on pin 53. Also looking at the edge connector, you can see the two pairs of pins, which correspond to the double ground, and double +5v.
From there, it was a matter of connecting up the power supply, adding in the power to the video board, connecting the RGBS connector, and powering it up. It was very cool to get a glimpse of Altered Beast!
And hello, it is a Datsu board. I’ve tried to google about these boards, and all that I could find out is that they seemed to be popular in Italy. They may have been made in Korea. There was another variation called ‘Mutant Warrior/Super Warrior‘. There was some posts about it in an Italian game forum mameitalia.net, and arcadeitalia.net . Google translate works fine enough to read, but they were in smaller places that couldn’t afford mainstream games, so enter the bootlegs. And this makes sense, as the board I got was from rural France.
I maybe had a picture for 20 seconds, it was frozen, then the screen went black. I power cycled, to nothing. I tried it again to a green screen. And again to a green screen. At this point I think it’s died. I let it rest for a few minutes, and try again. Nothing. I leave it powered up, and feel the processor, and it’s warm. It’s doing something, so I think. So I start to play with the video board, and as I change resolutions, I get an image!.. then it disappears. Power cycling, and changing resolutions occasionally gives me an image. I look more closely at the CPU board, and notice that it has 4 standoffs placed on each corner. There is nothing in the middle, and over the past 28 years the board is sagging.
In order to fix the sag, I decouple the two boards, and spread them out. I try it again, and it doesn’t show me anything. Eventually I play with all the video board settings, and manually set it to the RGBS input, and then the image stays! The board is running. I tweek some of the settings, and the pink goes away, and now it looks correct!
And even the intro animation is OK
OK, now it’s time to turn it off, and wire up the joystick.
The first step is to remove the joystick ball, and on the QANBA N1 you first flip it upside down, and remove the little cover.
to reveal the screwdriver slot to let you hold the stick in place as you unscrew the ball.
Now it pops off, and it’s really easy to remove the USB interface cables, and drag in the JAMMA cables. Again use a tester to tone out what goes where. DO NOT FOLLOW MY COLORING GUIDE. I’m pretty sure there is no colour standard, so just because mine is like this, yours will 99.9999% not be. The only common thing is that each of these buttons needs a ground.
My harness has a common ground for P1 and P2, so I just tapped up the end and tucked it in the joystick body. Now with wired up, I can put the joystick back together, and play!
And that is when I could finally see that something was wrong. I was doing pretty well, then in the 2nd level I saw this weird thing:
The sprites are working fine, and the gameplay continues. But eventually the wall of text effect went from the background to the foreground obscuring game play.
So no doubt something is bad on the board. I need to get it looked at, and see about first dumping and checking the EEPROMS. Next the RAM on the graphics board, may be suspect as well. I think the CPU is fine since it runs OK, I’m just unable to really see pass the wall.
For the heck of it, I went and got some powered speakers, and hooked them up:
And it sounds so different from the SEGA version. An inspection of the board shows that there is no YM2151, but rather a pair of YM2203’s and an OKI M5205 for the speech synths.
In retrospect, I probably should have gone with something like the arcade supergun. I didn’t know it was a thing unfortunately. My solution is more “traditional” , but it works.
