    JAMMA board from Raspberry PI

    I've made a JAMMA board out of a RPI. It runs RGB at 720x240 non interlaced video, has amplified mono sound and inputs for 2 players with 3 buttons each and 2 starts, one coin, service and test all wired to the GPIO. All power is through the JAMMA harness, no extra power supply or non standard wiring needed.

    I've built a basic linux/mame SD card image and have been testing and tweeking in order to release the software. I'll try and release it later this week. So far the software boots to a menu in around 26 seconds from power on. Boot time is only about 12 seconds but advance menu takes a while to load. It currently has 3 flavours of MAME and a version of FBA. The PI isn't crazy powerful but its able to run 60FPS for many games in portrait or landscape.

    It's not the be all and end all of emulators but the result is way better and more flexible than any arm based multiboard I've seen. Does most classics very nicely, newer stuff it does well include CPS2, most NEO GEO, Cave up to around the millenium etc. It cannot play a full mame set perfectly. I'd be interested to see what a native RPI low res game would be capable of...

    I'm using a hand made board at the moment but have redesigned it with CAD and will get a professional proto produced soon. If there's interest I may make more. I'll update when I've uploaded the software image in case anyone with a RPI wants to check it out.

    Any thoughts/feedback would be appreciated.


    ###### UPDATE 2016 #######

    Lots of things in the early posts in this thread are now out of date. I won't edit their content but wanted to update the first post a bit for the current state of the project. The easiest place to check for the latest info is now http://www.aussiearcade.com/showthre...te-information as this thread is very long.

    Quick guide to this thread:
    Information about version 2 of the hardware starts at page 16.

    Information about version 3 of hardware page 42.

    V3.1 software (pi2 and pi3) links from page 45.

    Running native resolutions for games would be a great feature (in the vein of GroovyMAME)

    Sounds interesting, +1 for groovymame.
    Winter is here and I'm still riding more than gaming, my current goal = 100,000 meters elevation gain for the year - well ahead so far

    Sounds cool mate, and i have a spare RPi sitting here doing nothing, waiting to be turned into something cool, so i'm ready to test/confirm anything you need...
