240p activation on 3DO Consoles with VP536

März 31st, 2017

3DO Consoles outputing 240i Signal but with adding a switch you can set it to 240p

It only works on 3DO consoles with the VDP536 Chip

Pin 52 progressive output (high 5V)

Pin 52 interlace output (low GND)

vdp_wiring

(red is 5V and yellow/purple leads to Pin 52)

 

I removed the RF-Unit and put the switch at the same position of the chanel switching

switch_inside

 

For usage power up in interlace mod (switch off) and after power on the console

switch on to activate the 240p Mode.

If you turn the console on with 240p activated (switch on) you only get a black picture.

Same when you change a disc and you close the console with 240p activated (switch on)

switch_outside

the case need some cleaning

Some pics

240i

(interlaced)

progressive is sharper and more stable and not shaking anymore :-)))

goDMD Clock Videogames Animation

März 21st, 2017

Last wekk I got a great gadget called goDMD Clock. The main usage of it is to show the time, date, temp and Pinball Animations from the DMD.

This new version is build with 2 RGB-Led Array in a total resolution of 128×32 Pixel.

 

You can order it here (If you have trouble with the shop mail me at info@wolfsoft.de)

Here you can see what I am talking about

After contact with the developer, he added  image rgb support to the editor :-)

https://bintray.com/sker65/pin2dmd/Editor#files

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.

create_custom_selection_use_128x32

 

After Pressing the Button: Save and apply to image you will see a window on top of the left png.

selected_area

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

batch_conversion_1

Mark the amount of png you want to crop and add them

batch_conversion_Advanced_Crop

 

Start Batch

batch_conversion_2_add_wanted_pics

now you have a lot of cutted pictures in the right resolution

target_images

now put a animaions.properties in this folder

notepad

After this try to import it in the pin2dmd editor under animations: Load Animations

 

Here you can download new Fonts for the goDMD Clock ArcadeFonts_go_DMD

 

Atari Jaguar “switchless” + Reset Addon + Multibios

März 16th, 2017

 

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.

 

 

jag_complete

(Overview)

jag_50_60_zoom

(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

Jaguar_R140_removed_60Hz
Attention If you use the PAL console you have to look downunder and remove a Resistor R140!

 

jag_reset_zoom

(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.

jag_rgb_led_zoom

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

 

Jaguar_Din_Hole

Jaguar_green_led

Jaguar_red_led

 

scart_PC-Engine_French_Layout_2016

(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:

jag_switchless_1

standard

jag_switchless_3

with button pressed a “little”

jag_switchless_4

(Sorry about wrong JBL speaking its BJL Loader ;-)

How to make a new NES Controller

November 10th, 2016

Today I got the NES Mini including a second Controller.

Modding PAL TurboGrafx

September 30th, 2016

I got some rare NOS TurboGrafx in 50Hz PAL Version.

img_0476
What can we do with this kind of PC-Engine

a) Speedup and change it to 60Hz

-Exchange Osscilator X201 to 21.47727Mhz
-cut Pcz80 Pin 15
-Solder wire from Pad pin 15 to Pin 22

img_0442

b) RGB bypass for best picture

I took the RGB Signal from C154 to C156 after removing the Kerkos. The wires leads directly to the Hu6260 RGB-Out

yellow wire to desoldered PIN 44 from HU6260 (C-SYNC)

I am using an old “french” pinput from the 90’th. So I have to reroute some cirquits

Desolder Din and cut GND on Partsside for make standard french Version of Din8 Cable working.

c) Jailbarfix

exchange C137 and C133 to 4,7uf/16V

d) jap/eng switch

you need to switch 8 wires (15,16,17,19,20,21,22,23). I done it with two  analog switches  MC14551BCP

internal PC Engine UWRC Receiver

September 6th, 2016

 

I used my IFU-30 Unit, so there was no need to remove the RF Unit. As I didn’t wanted some wires to the left or right side.

I put all needed connections to the rear side. Power, RGB-Out, Audio Out.

 

IMG_0073

 

I opened the RF-box removed the orignal switch and replaced it with UWRC switch.

Great feature, you can power off and on the PC-Engine via holding select and Run for around 1sec. Ideal for users of everdrives. Hope this feature will find his place in all new internal receivers from micro ;-)

NeoGeo AES 3-5 RGB Bypass with THS 3714

September 1st, 2016

thanks to arcadeTV we have a optimized Version with THS 3714 for NeoGeo AES :-)

-cut left side of the three 6,8k resistors for input rgb input of ths amplifier

-cut the left side of the three 75 ohm resistors for output to the din 8.1

-cut BF for sync output to the din 8.1

the perfect voltage divider values for bypass PCB :

R1,R2,R3=7,51k

R4,R5,R6=2,29k

@ AES 3-5 Mainboard Pin 3 Comp Video and Pin 7 C-Sync are the same on both you will get Comp. Video.

After the modification its is neogeo conform Pin3 comp. Video and Pin 7 C-Sync comming from the THS RGB Bypass PCB
