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.

Jaguar_RGB_Led_switchless

You will need:
-pic16f630
-button
-RGB-Led

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

(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

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:

standard

with button pressed a „little“
