| OpenJamma board - interest? |

Very interesting idea. I'd reconsider Mipps and aligning with this open project and its userbase: http://www.kickstarter.com/projects/gcw/gcw-zero-open-source-gaming-handheld Are you able to manage such a wide range of video outputs on the same inexpensive PCB? Would it make sense to have a JAMMA version then a HDMI version as a derivative board or are the video parts cheap enough that it doesn't matter? SD Card (up to 64Gb) |

The GCW runs on the chipset I thought of using originally. In fact I had stuff *running* on a jamma board with that exact chipset (JZ4755) last year. You can check the forums here for some history on that actually, as I did post a good few posts on that before I stopped posting due to one particular person spamming those posts who got subsequently got banned. I do know that chipset fairly well, as I did spend a few months looking at it. Its not quite as good as the one I'm going to use (although its fairly good for purpose). The ARM SoC i'm using has a lot more bells/whistles, and is the same price point, so no point going for the MIPS one imho. PCB will have all those outputs, as its pretty much built into the SoC, and connectors are cheap. I'll also have ethernet too (which I forgot to mention) SDXC support - will look at. (>32G SD is SDXC.) Unfortunately its covered by patents - ExFAT is microsoft encumbered, so while hardware wise should be ok, software wise might be issue's. Should be ok tentatively (I need to look closely at it). |

I would be interested in a couple for sure :cheers: |

U show me a jamma board that has a sd card slot, that I can stick a card in that has the entire neo-geo romset, that has VGA and stereo output and ill be interested. Also if you can make it emulate scan lines that would be a bonus! A Customizable front end would be a double bonus! |

I posted a link to this thread and we've been discussing it a little [here] One good suggestion that was made would be to add a Hirose DF1BZ-34DP-2.5DS connector that's used as the kick connector on CPS2/3 boards. Buttons 4-6 could then be connected to this although I would also suggest supporting five buttons from the JAMMA edge. The same connector is also used on 4P CPS2 boards for the controls for players 3 and 4. I thought if you added the connector for inputs 4-6 then it might be a good idea (if possible) if you/we could also be able to re-map/program the inputs and use it as a 4P connector for cabinets with three or four players. |
