After months (year?) of that stuff still packed (  oppps ), I've finally found time to test THE ultimate setup for me, which is :

Raspberry 3 -> Pi2Jamma + Pi2Scart  arrow



I was afraid to spend hours and hours doc reading to make all that stuff working... and ... finally NOT AT ALL. It's as easy as your ABC!

The result is just awesome! Full 15khz RGB / 60 Hz / 1:1 ratio pixel perfect
I've used few games who have perfectly smooth scrolling to test  ...





It's so smoothhhhhh  Kiss Pictures don't do justice... display looks amazing! And the emulation is reallllly good!  Kiss
I'll definitively use this setup to replace old computer or these crappy x in one chinese boards!

Thank Jochen for providing me the Pi2Scart adapter, which does a fantastic job (picture is brighter with it).

On the negative side, I had several time this bug, while browsing fast the games available on the USB stick :



Any idea what is the problem?

Oh, and I can't remove the front end music (can't find anything related to the sound in the option menu?). How to remove it ?

Finally will it be possible to configure the software to load one game only and disable the escape button?

Thx again for this amazing product!  Kiss Kiss Kiss

Thanks for your review and sorry for the late reply.

Issue 1 : software expects the pi2jamma  joystick. Just turn on the pi2scart mode to turn off the pi2jamma joystick in the software.

Issue 2 : the music is placed on the usb stick in folder menu-audio. Replace or delete this files. New version has additionally the features toggle music on / off and set volume.

Issue 3 : option - lock game or unlock game for disabling or enabling escape from game.

Hope this helps.
Jochen

Hello All,

After recently learning about the Pi2JAMMA, I ordered mine yesterday and joined this forum today. (I can't wait for the board to arrive)

My intent is to use the Retropie image on it (specifically the 'already-prepared' v0.8.1 image on strike-devices.net).

I do have a question on that image - is it also configured to try to find ROMS on a USB stick, or is this configured like the 'regular' Retropie at ~/RetroPie/roms/?

Brilliant, thank you.

And then a second question - is my assumption correct that pins 25/26 and c/d are being used for Player 1 Button 4/5 and Player 2 Button 4/5 respectively? (rather than N.C. as per the 'classic' JAMMA spec)

Correct

B6 is wired via extra screw terminals.

I finally got my Pi2JAMMA installed today (took a few months to sort out some other things).

I installed the Pi2JAMMA RetroPie image (I still had the retropie-4.3-pi2jamma-0_8_1.rar image) and am facing a few small challenges with the software:

- The Emulation Station menu seems to work well (at what I guess is 240p on my arcade monitor?) but when I launch any arcade game (I am using lr-mame-2003) it seems like the X-axis is scaled about 4x and the y-axis is scaled approx 2x (I attached 2 screenshots below). I have been scratching around in the RetroArch settings, but doesn't seem to make a change.

- When I press Coin-1, I (correctly) get a keyboard '5', however, when I press Coin-2, I don't get '6'. I checked my JAMMA harness for continuity, and all seems good on pins '16' and 'T' respectively. Is there somewhere in the software that I can review the pinout mappings? (I assume this maps to the GPIO somehow)

- I assume (once I fix my scaling issue) that 2-players will work just fine in MAME through the 'keyboard-style' controller that Pi2JAMMA is using. However, how does one get this to work for other systems? (eg: NES) (I guess this is more a Retropie-specific question rather than Pi2JAMMA, but this is my only 'keyboard-only' Retropie setup :-)

Thanks.

I installed the 4.4 image from Strike-Devices and can report that all is working well. Both the video scaling and Coin2 work as expected on my JAMMA cab (with standard resolution horizontally mounted monitor)
