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 :)

SD2IEC revisited

Okay, atfer moving to my new house I took the chance and put some of my old project back again on my desk. On of them is DIY kit for sd2iec project. It was project founded in the forum64 by shadowolf. The pcb layout is still one of the latest hw revisions.

But what was does this neat little device?

Just simple, it`s sd card drive for the good old commodore C64 :) Imagine how many disk image you can put on a 1GB sd card...hundreds...nooo.....thousands... noooo... milllliooonss... :))

Back to the Roots - Commodore C64 DTV

Hey Folks,

back to the roots again. For those born > 1980: This is Commodore 64 built-in a Competition Pro like case. The competition pro was / is the best joystick for 9pin like protocols (Atari, Amiga, etc). Additionally the C64 DTV starts with a menu with 30 games. This games loads in 0 seconds. This is comparing to disc drives like 1541 incedrible :) Of course this C64 dtv is modable. I've added:

- two external joystick ports
- one disc drive port
- PS2 keyboard interface

and a so called dtv trans cable. With this cable the c64 dtv can be flashed with new (better) games.




Jep, the PCB is scrap, very cheap production and a horror to soldier.



The nearly no space for the cable. So watch out.


Fitting all the ports in the case.


First test...





This mod makes this c64 dtv to a almost fully functional Commodore C64 :)

C64 DTV Mod in a 1541-II Floppy in black

Found an old mod I was take part on ebay. I was soldiering the internals and connectors to the PCB. It's a really good handcraft piece and definitive worth it's money. It was designed in a way that the complete roof with DTV of the 1541-II can be unplugged. The 1541-II can be used with and without the DTV. It has built-in keyboard interface, two additional game ports, power supply jack, IEC connector of course, Video connector and stereo (!) jack. Nice work Gunther!

C64 DTV mod with external sd2iec drive

Feature list:

- external sd2iec drive
- 2 joystick ports
- IEC port
- power jack
- PS2 keyboard connector
- color fix
- twister



dtvtrans cable is connected for flashing new games. dtvtrans was loaded via sd2iec drive.

sd2iec drive has extra power supply

C64 dtv mod with internal sd2iec drive

Feature list

- SMD color fix
- Keyboard fix (called Twister)
- Power jack
- internal sd2iec (based on mmc2iec) drive with led and disk change button
- PS/2 Keyboard connector
- 2 joystick ports
- flash fix

SD2IEC Drive for Commodore C64

So, here some pics of my sd2iec drive. It works with normal sd cards and D64 image files. The image files can be downloaded from the internet, saved on the sd card and then loaded directly in the C64.


Tape port connector is only for power purposes.
