Raspberry Pi with 15khz RGB Scart output via Pi2Jamma

I was asked quite often if a 15khz Scart output for the Raspberry Pi can be made. The 15 khz video output RGB scart is generated via gpio,  forwarded to Pi2Jamma and the Supergun-MAK-Strike provides neogeo ports and scart interface.

PiJamma Installing GPIO Driver

Here`s a little tutorial for installing Arcade Controls via Raspberry GPIO Interface with PiJamma. 

Download driver and installation guide from PiJamma Page

http://arcadeforge.net/download/PiJamma-retro-gaming-with-raspberry-pi.zip


Directory retrogame contains all needed files. We did use Chameleon Pi during this installation. Use is „zx“ and password „spectrum“, this applies also for the network login. We assume that folder „retrogame“ is under  „/home/zx“. 

Steps
1.    Open Terminal.
2.    Activate uinput Kernal „sudo sh -c 'echo uinput >> /etc/modules“
3.    „cd /home/zx/retrogame“
4.    „sudo ./retrogame &“

To activate retrogame automatically durinf bootup:

1.    „sudo nano /etc/rc.local“
2.    Before last “exit o” insert „/home/zx/retrogame/retrogame &“
3.    „sudo reboot“

PiJamma for Raspberry Pi - Sound Installation

I´ve made some progressfor the sound installation of the PiJamma. PiJamma can be used in combination with Raspberry Pi in Arcade Cabs and Bartops for retro and arcade gaming installations.

Here is a quick shot of my test bench.

This time I just makde some videos explaning the sound interface.

Further I updated the documentation for Arcade PiJamma and Raspberry Pi

PiJamma Enclosure Work

Almost forget to blog the Raspberry Pi PiJamma Enclosure work. It`s laser engraved and notifies the various connectors. PiJamma helps to build your Arcade Bartop or Cab. It comes with a Jamma Interface as well with C64 and Amiga plus Neogeo Gamecontroller Port Connectors. Raspberry Pi offers various retro console emulators and arcade machine emulator MAME (M.A.M.E.)

Our Raspberry Pi addon called PiJamma was mentioned on hackaday. PiJamma is used in an arcade stick.

ArcadeForge.de PiJamma Project : Building a Raspberry Pi Arcade Stick DTV

PiJamma for Raspberry Pi

 Earlier we announced the PiJamma Project. PiJamma is an add-on PCB for the Raspberry PI that simplifies connecting retro hardware like old game controllers or jamma arcade bartop or cabs.

Youtube Video

 Today my idea was to built a Arcade Stick that can be directly plugged to TV like the old good C64 DTV, but now with  "everything".

Planned Features:

- Acryl Arcade Stick: all the nice tech stuff can be shown.
- Raspberry PI with 32Gb SD, packed with emu stuff plus WLAN Adapter
- PiJamma PCB for connecting Arcade Controls
- HDM plug
- USB plug
- PSU connector
- LED Modded buttons with new Acryl holder
- Buttons with inlay artwork
- Artwork
- Aluminium Panel
- NeoGeo 4 Button Layout
- Sanwa JLF Stick unit with Link. Stick can be pulled off.

 Here the stock unit and the button with inlay artwork.

 Aluminium Panel with Stick unit.

 LED modded button. Acryl holder for 5mm LEDS.

 Checking where to place the components.

 One sees here the interface panel with USB, HDMI and power supply interface. Rapsberry PI will be powered via PiJamma.

 USB interface and HDMI interface connected to the interface panel and Raspberry Pi.

 Arcade Controls connected to the PiJamma. Signals will be forwarded to Rasperry Pi GPIO interface. Additionally the LED Mod was installed. 

 GPIO interface connected.

 The stick unit can be detached. So transport is more easy.

 LED mod off

 LED mod on, ok, it`s better to make such pics when it`s dark.

 close-up of the panel interface with USB, Power and HDMI.

 Just connected a keyboard or USB stick to the Raspberry Pi Arcade Stick.

First test with Commodore C64 Giana Sisters. :)

Raspberry PI for Arcade Jamma Adapter with C64 / Atari / Negeo Joystick Port

Hey, 

this is my new project for the Raspberry PI. I`m still searching for a good name :) Anyone?

EDIT : Name found :) The project is called PiJamma. It`s available in our online shop http://www.arcadeforge.de

It`s a kind of Arcade  Jamma Adapter with controller game ports for C64 / Amiga / Atari and Neogeo style sticks. Additionally it has various connector break-outs like screw terminals to make your modding life more easy.

You see here the Raspberry PI with the Jamma Adapter.

Features :

- Raspberry pi GPIO Connector

- Jamma Interface

- Screw Terminals for all kind of signals

- Game controller Port DSUB 9 pin for Amiga, C64, Atari, etc

- Game controller Port for DSUB 16 pin for NeoGeo Controller sticks

- 3 buttons for controlling the emulators. Ie. take Start Player 1, Start Player 2 and Coin for Arcade emulator MAME

- Simple PSU Plug for 5V

- Extended PSU Molex connector for 12V and 5V

- 6 Pin Audio connector to connect a external amplifier. This way the Arduino Line Level sound can used in Arcade cabinets or bartops with speakers only.

- On and Off switch with LED

Ok, here some pics using the connectors.

Raspberry pi audio headphone connector to chinch. The Audio coming from Raspberry pi is line level. I`ve decided to go with extern amplifiers. So the user can decide to use high performance amplifier or home entertainment system or whatever. The design goal is to offer a wide range of use cases and not stick on one sound interface solution.

This board uses the GPIO interface for Arcade Controls. This way an additional Keyboard Encoder like Dual Strike or Key Strike is not needed. The pin count of the GPIO is limited. If someones wants six button 2 Player controls, so Keyboard Encoders can still be used via the USB Port of the Raspberry Pi. So again, no need to make the board expensive. The user decides what he wants.

But let`s face the Game controller Ports. In the picture one sees the famous competition Pro for the even more famous Commodore C64.

I`ve added here the audio breakout. Pinout is

- 12V

- GND

- Audio Line Level Left

- Speaker-

- Audio Line Level Right

- Speaker+

5V is available via Screw Terminal. Using 12V via this connector means that 12V must provided to the board via the Molex Connector. On the picture a sample Mono Amp is shown.

On the Picture a sample Stereo Amp is shown.

See here a simple 12V and 5V PSU. As said before a simple 5V PSU can be used via the basic PSU Plug. In this case the sound can grabbed from the HDMI or the headphone jacks to your own amplifier. 

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. The next post will shown some video adapter to get from HDMI a VGA signal with Scanlines or even RGBS for CRT or Arcade CRTs. 

Thanks for your attention. Comments are welcome :)
