PiJamma : Raspberry Pi Arcade Interface Project

[bencao74]

I`ve seen some very nice projects with Raspberry Pi. So I took some of the Raspberry Pi and began to play with them. I like the features for arcade and retro gaming offered by such a platform.

So first I tried Chameleon and the Adafruit Arcade Controls Tutorial. Finally I ended up in some project goals.

I want a thin PCB addon with break-outs for interfaces like Power, Audio, Video, Gamecontroller plus some common gamecontroller plugs. Additonally the addon should offer modding interface.

- Thin Client is realized by using gpio for game controller interfaces. Screw Terminals are on-board for connecting Keyboard Encoder
- Audio : Chinch input for line level and pinheader plus screw terminal output for amps and speaker.
- Game Controller Interface for Commodore Amiga, C64 and Atari style 9 pin Joystick
- Game Controller Interface for Neogeo style 15 pin Joystick
- Jamma Interface for use in Bartops or Arcade Cabs.
- Video must be converted from HDMI to your wanted setup. General purpose screw terminals are offered to map RGBS to JAMMA interface
- Power : 5V interface with simple plug (not this USB tiny plug) with on and off switch
- Power 12V and 5V interface for using this project with external 12V amplifier or in Arcade Setups.

Enough theory, here are the pics













Some examples for the use of connectors

AUDIO, GPIO



C64 Joystick, GPIO


Connect your Rapsberry Pi to your TV and just start playing with the C64 Joystick your favourite console emulator. GPIO are used for the Gamecontroller Inputs.

C64 Joystick, GPIO, Audio plus Mono Amp


C64 Joystick, GPIO, Audio plus Stereo Amp


The Audio interface comes with pinout
 - 12V
- GND
- Audio Line Level Left
- Speaker-
- Audio Line Level Right
- Speaker+


C64 Joystick, GPIO, Audio plus Stereo Amp; 12V and 5V PSU


A short word about the video out. Raspberry offers HDMI and composite out. It would have been so nice to see VGA or something more sophisticated analogue signal. Anyway the Raspberry foundation decided not to support VGA. So video adapters are needed to convert HDMI to a VGA signal with Scanlines or even RGBS for CRTs.

love it !

very cool !

[bencao74]

Thanks a lot.

I`ve made an Arcade Stick with the PiJamma and Raspberry Pi.

This was the first tests, so I just described the features in german language. English version will follow.

I've the Pi running in my cab too, but with a MiniPac interface over USB. Amp is directly driven from the Pi.

[bencao74]

What type of screen do you have? LCD with HDMI?

[Blanka]

Yes,
Had to find out the config tweak: I like blocky, and default the OpenGL scaler is anti-aliasing.

[bencao74]

ohh, cool. Could you post your config details`?

[Blanka]

I plan to write a how-to.
I gathered information from so many sources, it really asks for a clean How-To guide.

[bencao74]

would be awesome. finally it`s a nice idea to offer an image for download. If you need help, just pm me.

awesome !

I`ve been working to put the reoslution down to 480 lines. I`ve used the cheap available hdmi2vga converter, but succeeded only to go to 768 lines. Goal was to have a nice resolution for emulating scanlines. Any input here is appreciated.

You know what would be REALLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLY awesome?


If someone could take the Raspberry Pi and attach storage for Video/Audio files as well as all connections for Dragon's Lair.

That way the LD player and the original board can be removed, thus bulletproofing with no moving parts.

sounds do-able, i mean it can play 1080p movies with XBMC, so capacity enough i would say

max SD card is 32 Gb, more than enough to host the video files..

i dont have the knowledge though, but is there a port of Daphne for Linux ?

If so, i guess it could run on this hardware.
