Arpicade JAMMA adapter

You can change the Attract-Mode (the front end software) layout(s) from within the frontend.  Once it has booted and you're at the game selection menu press 'tab' on keyboard or the cab test button/switch to open Attract-Modes menus.  Navigate to the option 'Displays', then select the display you want to change (there's different displays for all games, just arcade games, and each console etc - they're all able to be changed independently of each other).  In the Display Edit menu selecting 'Layout' will let you scroll between the installed layouts using up/down on joystick.  {WARNING: if it is installed do not select the Invaders layout as it breaks something and causes issues - if you see it scroll past it}

Once you have the displays set the way you like access the service menu (f4 or service from the game select menu) and reboot or shutdown from there to make sure your changes are written to the SD card.

Not a problem to move the audio to the Pi 3.5mm output rather than the DAC when using HDMI out.  Just need to run one command on the command line once to set the output to the right channel of the Pi.  The only downside to doing this is a possible slight audio quality reduction (unlikely to be noticed in most cases).

TO do the cahnge plug in a keybnoard prior to booting up and once at teh menus use 'f4' to exit both menus to the command line then type:

amixer cset numid=3 1       

(press enter) then to reboot type:

sudo reboot

(press enter again)

Once rebooted the audio should have moved to the Pi 3.5mm output rather than the HDMI (DAC) output.

Arcade roms should be placed in 

/boot/roms/*/%.zip 

where "*" is the emulator and "%" is the game.  Roms must be in the correct directories and named and zipped 

according to the conventions of the relevant emulator.  

The exception to the arcade rom storage system is Daphne, its roms are stored in /boot/roms/daphne/rom and 

framefiles in /boot/roms/daphne/framefile/(directory with same name as the rom) due to the way the emulator 

works. 

Console roms in:  

/boot/roms/consoles/*/%.ext  

where "*" is the emulator, "%" is the game and “ext” is the relevant extension.  Roms must be in the correct 

directories and generally must be unzipped (except advmess).  Names of console roms are not critical as they 

are for arcade roms, name them so you can identify them in the menu. 

Rom scanning is automatic at startup by default but can also be done manually through the service menu. 

Make sure to safely remove/eject your SD card before pulling it out of your PC.

• Hold 1P Start for a couple of seconds + 2P Start exits a game back to the menu. 
• Hold 1P Start for a couple of seconds + P1B1    == Credit 
• Hold 1P Start for a couple of seconds + P1 Joy Down  == Pause/Unpause 
• Hold 1P Start for a couple of seconds + P1 Joy Right == MAME menus (MAME only)

 Each version of MAME included has it's strengths and weaknesses, to get the most out of the system a bit of 

mixing and matching is required. 

    MAME 0.172 is the latest recommended version and has the best emulation quality although it's performance 

is highly variable between titles. 

    AdvanceMAME has many more options and more accurate emulation than MAME4All or 

MAME2003/MAME078 as well as better performance than MAME0172. 

    Mame4all has faster emulation and is useful for any games which run slow in the other emulators, although it 

has the least accurate emulation of the MAMEs included (it is based on 15 year old MAME). 

    MAME072 (MAME2003 Retroarch core) has hacks built in to speed up the emulation of some Midway DCS 

audio titles.  This emulator is slowly improving and is still under active development.  It is also very good at 

mapping analog controls to digital JAMMA controls.

 I recommend exiting a game so as you are at the game menu before shutting down your cabinet.  It should not 

be necessary to run a shutdown script as while at the game menu there are no writes to the SD card to be 

interrupted to corrupt the card.  If you make changes to your systems settings I recommend a shutdown or 

reboot to ensure those changes are written to the SD card.  (but have a backup just in case things go bad some 

day)

  You start by setting the Pi to the resolution you want in 

        /boot/config.txt 

    using the 

        hdmi_mode= 

    setting you desire.  This will ensure the hardware boots at the resolution you want and is the first thing to do.  

    You will then need to edit the service menu launcher script (boot/launchers/servMenu.sh) to uncomment 

(remove the ‘#’ hash) the highres options.  After a reboot the option will be available in the service menu.  When 

the relevant option is selected the system will reconfigure itself and reboot in the selected settings.

If your cab has no service button you will need to plug in a USB keyboard before powering up.  Once the system 

has booted press either 'service'(cabside) or (on keyboard) 'left' or 'right'  until you're at the service menu.  Use 

the joystick to select low res vertical and the system will reconfigure itself and reboot setup vertical.  You will 

probably also want to change the theme in Attract-Mode to a vertical one. 

If you need to flip the picture to suit your monitor mounting: 

In the file /boot/config.txt  

     display_rotate=2 

will flip the image should your monitor mounting be upside down.

Make the boot splash you want and copy it to the memory card in the boot partition as "splash.png".  Boot Pi 

with USB keyboard attached, wait for menu to load, press "esc" to exit menu and copy your new boot splash to 

the system as a super user: 

      sudo cp /boot/splash.png /etc/splash.png 

   Then reboot to see if it worked out how you wanted. 

      sudo reboot 

   This can also now be achieved from Attract-Mode (cab service button OR left or right on a keyboard to find the 

service menu) or advmenu using the F8 menu and the /boot/config-updater folder by placing the new picture you 

want in the folder as splash.png the pressing F8 in advmenu and using the option to update the splash.

The games that originally had freeplay options in dip switches can be set using the mame menus or in 

AdvanceMAME only through the config file line: 

        misc_freeplay yes 

   however not all games had a freeplay mode and also a lot of games do not show an attract mode when set to 

freeplay so you will probably want a coin slot/button or button combo to add credits in mame. 

   Games which used test menus can have their test menus accessed by pressing the cabs Test button/switch or 

'F2' on a keyboard during the game. 

   You can also use the shortcut P1 Start (long hold) + Button 1 for credits. 

 Different versions of MAME use different romsets, some roms will work across many versions of MAME others 

won't.  You can convert romsets using programs like romcenter and datfiles for the emulators.

The image is sized for an 8 gig card as it's the minimum usable size.  To use a bigger card you will need to use 

the partitioning program of your choice to move the 2nd partition to the end of the image and resize the first 

partition to fill the newly created space in the middle of the card.  Before resizing the first partition copy it's 

contents to your computer as resizing will destroy the contents, then copy it back when resized and you should 

have a working image.

You need to adjust the resolution in /boot/config.txt to high res also uncomment the change to highres options in 

/boot/launchers/servMenu.sh and adjust the system to highres in the Attract-Mode service menu (left/right on the 

keyboard or cab service button in the menu to find the service menu).  Do not launch a game before changing 

the resolution like this or the launcher script could change the res to one unsuited to your monitor.

You can actually edit the game list from the game list.  Press 'e' on a keyboard to edit the highlighted option.

I don't recommend playing around with the terminal unless you know what you're doing but you can press 'f4' to exit the game select menu then 'f4' again to exit the service menu (which also includes an option to scan the roms) to a terminal.  Please note, any hand made edits to the game list will be lost next time the rom scanner is run.
