Making of Snow-White and the seven Shockers…

Montag, Juni 14th, 2010

I found some NeoGeo Cases here and cleaned them up with the help of my dishwasher.

They have a lot of scratches and as I am not a friend of black – I prefer WHITE – like the great PC-Engine one of my favorite Consoles. I make use of white spray on a good old NeoGeo AES.

After some spraying it looks like this:

SNES CIC switchless Mod at a USA/japanese SNES

Montag, Juni 14th, 2010

Thanks to Maximilian Rehkopf alias ikari_01 we can proudly present a new switchless Mod for the SNES.

Today I am using a japanese SNES. It works with a USA SNES too. It has the same layout.

Here you can find more information:

The mod is using a PIC 16F630 with the following code: supercic

There are two ways to get the new CIC working.

a) with original CIC still onboard

To get the supercic working you have to lift the following pins of the original CIC.

Pin 1,2,10 and 11

b) removing the original CIC and add a 10k from Pin 8 to GND.

I will make use of way b) here:

Remove the original CIC (here you can see some pictures of a PAL SNES.
Its the same at the japanese/USA SNES.

supercic_2

The usual 50/60Hz Pins:

You have to lift PPU2 Pin 30 and lift PPU1 Pin 24 and wire it together to Pin 12 @Pic12f630.

The Console is set to 60Hz if you set both Pins to GND
The Console is set to 50Hz if you set both Pins to 5V

supercic_4

Here you can see the wiring of the pic with ikari_01 Code:

PIC_cic_pinout

First we have to put some 5V at the PIC.

You can set the PIC into 2 Modes

a) Pin 4 to 5V (I used this Mode, see the red wire)
b) Pin 4 to GND

And please set Pin 7 To 5V (PIC is set to RGB-LED Mode (common anode).
Take 5V From the Pin 81 of the nearby IC

To do the LED Mod you have to remove the original LED at the controller port.
You can shortcut the original Resistor of the LED, if you want the full power of the RGB-LED ;-)
With a RGB Led you can choose 2 of the 3 colors you wish. I am using the normal colors red and green.

cic_jap_Leds

You can use two different LEDs:

a) a Duo-Led with common cathode (GND)
You have to set Pin 7 of the PIC16F630 to GND

b) a RGB-Led with common anode (plus)

Look here for a picture:

Some Info about the usage of the superCIC.

You can change between 50/60Hz and Auto Function by pressing the Reset Button for longer as around 0,5 sec. The current Status is shown by the DUO-LED. (red=60Hz, green 50Hz, orange=Auto).
After releasing the Reset Button the mode will be active. The SNES will not reset at this moment.

a) 50Hz Mode is active (green)

If you insert a PAL-Game, it will start with 50Hz
If you insert a NTSC-Game, it will start with 50Hz (if Pin 4 is set GND)
If you insert a NTSC-Game, it will start with 60Hz and switches to 50Hz after 9 sec. (if Pin 4 is set 5V)
If you insert a Game without CIC, it will start with 50Hz

b) 60Hz Mode is actice (red)

If you insert a NTSC-Game, it will start with 60Hz
If you insert a PAL-Game, it will start with 60Hz (if Pin 4 is set GND)
If you insert a PAL-Game, it will start with 50Hz and switches to 60Hz after 9 sec. (if Pin 4 is set 5V)
If you insert a Game without CIC, it will start with 60Hz

c) Auto Mode is actice (orange)

starting the Game in its native frequence.

If you insert a NTSC-Game, it will start with 60Hz
If you insert a PAL-Game, it will start with 50Hz
If you insert a Game without CIC, it will start with 60Hz
Here you can see a video, how the switching is working:

Here you can see a US-Unit with a RGB Led using blau and red part of the LED:

Sega Mega Drive 1 switchles mod

Montag, Juni 14th, 2010

Today I got a PAL SMD1 Console. I tried sebs code as several times before to make a switchless mod.

You have to cut 3 circuits and need a 3mm Duo-Led for displaying.

NeoGeo Oldstyle Button LED mod

Freitag, Juni 4th, 2010

After surfing the www for neogeo… I found a modified NeoGeo Joyboard with LEDs.

A great Idea, and some dremel work later…

Nothing new for me. The Buttons in the oldstyle Boards are the same as the NeoGeo Reset Button.
I done this mod weeks ago.  Some RGB-LEDs and Resistors and done…

I done some upgrade and make the lights switchable.

I am using a analog switch MC14551B to make three modes possible

a) lights off

b) Light on button press

c) all lights on
