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)

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.

Hey,

 its regular with roms on card.

Cheers

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)

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/?
