raspberry modding is everywhere. So we put a raspberry in a NeoGeo Oldstyle Arcade Stick for presentation at GamesCom 2017, so the younger games can get in touch with the neo-geo Games and not only with the look. With the right feeling a original NeoGeo Controller
The position makes it possible to use the onboard USB Ports and network connector.
First some dremel work to make it fit into the neogeo arcadestick case
then a hdmi slim extension and a usb cable
As the NeoGeo X Controller is a standard USB Controller it was possible to connect the usb part directly to one usb connector of the pi
in the future it could be possible to make the buttons directly to GPIO Ports
Atari 800 was my first computer after Sinclair ZX81 and its time to make the picture better. After checking the A/V Out it contains Video and S-Video in a good qualitiy. So i decided to replace the original DIN Connector and replace it with a DIN 13 like used in Atari 7800 french and Atari ST. I used some not needed pins from the Din 13 to put in Video and S-Video too. So its possible to use RGB-Output via a standard french Atari 7800 RGB Cable and with a special Cable made I can use Video and S-Video too via the same connector.
To put the DIN 13 in the right position i need some plastic and drilled holes downunder to make the Din connectors accessable
replaced DIN 5 to DIN13

because of no space at the CPU Board I needed to move the Sophia Board to another place. I uses some ribbon extension like this
and here we go. In front you see incognito board too
Here you will find a package including one demofile. gridlee You only have to change variable base to your path were the package extracted
To do some animations for goDMD you have to use mame. I am using groovymame, because it can be set to output native pixel resolution of the games. So you will get a pixelperfect output for the goDMD.
start mame via commandline: groovymame -mngwrite griddle.mng griddle and do some gaming. After exit you will find a griddle.mng.
To split the griddle.mng into pictures I used a programm advmng
start it in the path where the griddle.mng via commandline: advmng.exe -x griddle.mng
After this you will get a lot of pictures like: gridlee-00000022.png (Resolution: 245×240)
With the help of irfanview (a pictureviewer) you can create a custom selection (under edit) with Width: 128 and Height: 32.
After Pressing the Button: Save and apply to image you will see a window on top of the left png.
Move it with the help of arrowkeys to the area of interest
In Top Line you see (Selection: 0,0) this marks the X,Y Position. You have to enter these values in
Under File: Batch conversion (set to PNG Output Format) and press Advanced Button: Here you can set the X-pos, Y-pos Position
Mark the amount of png you want to crop and add them
Start Batch
now you have a lot of cutted pictures in the right resolution
now put a animaions.properties in this folder
After this try to import it in the pin2dmd editor under animations: Load Animations
I got a white “dental” case and its time to make the jaguar ready for 2017
The title is something strange, but its comming from a Sega Saturn Mod years ago (the code is based on this). The Saturn reset button is used for change region and 50/60Hz.
I removed the RF-Unit to put my “standard” DIN Connector and for adding a button instead of the chanel selector. With the help of this tiny button you can select between 50/60Hz.
(Overview)
(U25 Pin 11 sets the Console between 50 Hz (GND) and 60Hz (5V)
I used a US 60Hz Jaguar for modding, so you have only to solder this wire to Pin 11
Attention If you use the PAL console you have to look downunder and remove a Resistor R140!
(The Reset Line you will find U9 Pin 13 (GND = reset)
I removed the original LED and put instead a RGB-Led.
I set red for 60Hz and green for 50Hz.
If you find blue better, no problemo. But red/gn are the real colors of the Jaguar used in their countrys.
Usage:
Its like the switchless Mod for the Sega Saturn.
a) When you push the button for a moment. The Jaguar will do a reset
b) you push and hold the button. Now the Color of the LED will toogle between green and red. When you release the button
at red -> Jaguar Resets and starts with 60Hz
at green -> Jaguar Resets and starts with 50Hz
(bigger hole for Din RGB-Connector)
(RGB-Pinout)
(Reset button)
(overview)
(my standard Din Pinout, based on modified 5 Pin Din PC-Engine + 3 more for RGB)
Its time to add a 2nd Bios to the Jaguar.
You have to remove the original Jaguar Bios and use a DIP 32 socket.
With the help of a 29f040 FlashRom I added jagbios and BJL1.06
You need to concat the bios files:
Use: windows command: copy /B jagbios.bin + jagbios.bin + jagbios.bin + BJL106.bin 4in1bios.bin
and burn 4in1bios.bin to the 29F040 FlashRom
(overview)
Update 23.6.2017
I put a switch beneath the Power Switch to make it like a “real switchless” mod.
So the Power switch can pressed a litte to:
change 50/60
Reset
switch between original Bios and BJL
OR
Press it more deep to Power Off and Power ON like normal
I used a little switch with a ball at the end and put it inside like this:
