OpenJamma board - interest?

[Nephasth]

Sandy...

[PL1]

You say it, we play it on All Request Wednesday.

This one goes out from Nep to that special someone he's missing. . . .


Hope things work out for you crazy kids as good as they do in the movie.

I admit, I LOLed.

*walks away slowly, unawares of what the hell anyone is talking about*

yes, I got the park reference; still not sure what anyone else is talking about. 

[Nephasth]

 

Good one Scott.

[yotsuya]

*walks away slowly, unawares of what the hell anyone is talking about*

You at least got the park reference, right?

[launton]

Yes, an update would be good.  Don't want openjamma to think it's not 'the one that we want'

[shanghaiguide]

Update is that there is no update at the moment, as we need to "get stuff done(tm)".
So..., we're doing that.

Unfortunately getting stuff done doesn't really make for interesting times, but we are alive, and doing stuff, so progress is happening slowly but surely.

How's the progress? 

I know, good things come to those who wait, I'm waiting patiently.

must be vacation time in china??

[JMB]

Any progress?

[nagamitsu]

Been meaning to send him a message on Facebook to ask also. August was a potential release for the board, but not sure if things are on schedule with it, would love to hear how progress is going.

Well, it's easy to lose motivation when Sandheaver tells you you're doing it wrong 40 times...

I have a different attitude toward it; use an FPGA to output RGB analog video and to run the game.  Describe the hardware for the games you want to emulate, and the FPGA can do it all.  Provide the roms & samples, and you're there.  This is how the 60-in-1 board does it, I think, but they used terrible samples for a few games and the sound quality suffers accordingly.

If you describe the hardware accurately, an FPGA can handle all of the digital stuff, and output the proper video signal to drive an arcade monitor.  For example, the FPGA Arcade does exactly this.

This type of solution requires a lot more knowledge than I possess.  JROK over on KLOV forums could do it.

If the OpenJAMMA board can run with minimal frame latency and drive an arcade monitor directly I honestly don't care how it's implemented, and it doesn't matter how it's implemented.

The 60-in-1 board actually uses an ARM processor, running an old version of MAME.

Really?  Mine has an Intel PXA255 and an Altera MAX II.  Are you speaking of another chip I'm not seeing or do I have a different version?

The PXA255 is a 5th generation ARM processor, which may be branded as "Marvell" or "Intel". Intel sold the assets for the PXA to Marvell a few years back. The chip has the markings "C200" which classifies it as the 200MHZ version.

The Altera Max II is a CPLD, not an FPGA. CPLDs typically have far fewer gates ("course grain") and are not intended for large digital designs.

[Rigby]

I am corrected.

[CraftyMech]

With regards to the FPGA approach, I think the issue when you are talking about a lot of games is the complexity and magnitude of that undertaking. JROK spent considerable time reverse engineering the Williams platform, and tweaking the design of his Multi-Williams board to get the game timing as close to the original as possible. Imagine the effort to implement just the set of games on the 60-in-1 for example, where you have a variety of platforms: Stern, Midway, Capcom, Nintendo, etc.. If you focused on one system, such as Capcom CPS-1, you would have more bang for the buck, but there is no way an FPGA implementation will ever touch the size of library that a basic MAME setup is capable of running, and emulating quite well.

I agree; it would be an incredible undertaking, indeed, but I don't think it would be impossible.  Many games share components, such as the Z80, for example.  I also don't really think that one would want to put all of mame on a single board; I question the legitimacy of ideas to put hundreds or thousands of games on a single cabinet.  I'd be happy with about 8 vertical games on one board, as I don't really enjoy more than about 8 of them.

I favor the FPGA idea so much for a couple reasons: A) it's fascinating to me to think that you can re-implement the old hardware on a chip.  B) there is 0 frame latency; it's the same as playing on actual hardware; no emulation.

I'm talking too much, again.

Finally had a chance to catch up on this thread. shanghaiguide, you really got a good one here!  All the personalities showed up for this...driverman, Xiaou2, sandheaver... entertaining!

I just signed up for the newsletter, and like I told you in PM, I'd be really interested in picking up one or two of these. Hopefully development is going well.

This might have been discussed earlier (i might have skipped past it), but what are the physical dimensions of the board? Will it be enclosed in a case?

[nagamitsu]

I'd just be happy knowing there is progress and to hear maybe it is a month or two away from completion. Throw us a bone!

not feeling optimistic.

[nagamitsu]

That's just a few days ago though, that's not bad.  I have fingers crossed still, not wanting to buy one of those X number in one boards. Plugging away with my one single game PCB for now. 

[nagamitsu]

Facebook page shows that the board is still in the works, some hardware issues, someone hired in to help with that. Estimating another 2 months for dev boards.

Maybe one in time for Xmas? 

[sharpfork]

Is this you guys or someone else?  JAMMA board that runs android on arm: http://imageupper.com/g/?galID=S020001007I13789101722368129&n=1

[yotsuya]

  for update?

[opt2not]

I tried PM'ing him not too long ago, didn't get a response. It's possible he abandoned this venture.

[Nianticcardplayer]

Still no updates? Hoping this would have gotten back on track

[paigeoliver]

This is dead. It was far inferior to the x86 based xxxx in 1 hardware to begin with anyway. I just wish there was someplace that sold that with drivers and blank hard drives.

We have been working on a Mini ITX based board set up for a while... have everything done except... the Jamma connection, maybe the Kade guys can fill that in

this. It's a shame that ultracade didn't take off, that "I/O board" was really well setup and could have been used for anything since it just emulated a keyboard/mouse but plugged right into JAMMA.

There are more than enough dedicated cpu jamma boards out there for you to analyze. Hell, i saw one just the other day that had rigged two (s)nes shift registers for the controller input. I'm assuming it simply used sneskey or similar for the controls.

Most of the ones that have been out there though aren't too popular. They are still just ghetto rigged solutions for the same things that your average byoac member had done at the DIY level with minimal effort.

Even so, that still leaves your 15khz support issue.

[paigeoliver]

I have a Target Terror I/O board that seems to do the same thing.

According to the Facebook page on September 6, "We are alive, although we're behind schedule. Things are progressing though!"

yeah i kinda looked at that too. I thought the same with the PGA golf I/O not sure about how it's emulated though. it's USB, so i plugged it into an XP machine and it detects and installs an HID but that's about it. doesn't emulate a keyboard or anything as far as i could tell...plus it's not jamma.

well, here's to still hoping. 

[Dariusz]

Is there any WIP news on the openJAMMA project or has the project been scrapped?

[yotsuya]

I was just thinking about this on my drive home and was going to  for updates!

[JMB]

Nothing on their Facebook page since Sept 5th. I'd guess this was dead. Too bad.

[yotsuya]

Uh,  for any updates/signs of life....

[opt2not]

This is most likely dead bro.
