[Console Repair/Mod Center / SNES2PCE pad converter]

If anybody wants to make a SNES2PCE pad converter I have posted below my version.

There is a CPU in need of programing.
This just provides clocks etc
Converts a Snes pad to either a 2way or 6way PCE pad selected by a switch.
The 2way has I and II (Y & B) mirrored with auto fire on X & A.
Select is also mapped to the right shoulder button.
Changing the schematic you can change the above configuration.

Will need a 1 to 1 8pin plug cable. Make sure it's is 1to 1 as there are plenty with swapped pins.

[Console Repair/Mod Center / Pc Engine GT 2500mAh Lipo battery pack]

Installed a 2500mAh Lipo battery pack into my GT.
This is removable but also can be charged when cover removed.
I swap one then charge the other.
I also installed a Gammatronix programmable led battery indicator
Battery pack and charger purchased

Mating cable for battery

First removed all AA battery parts and plastic posts in the battery compartment.

The cover also needs reducing as the battery pack is just too thick with these bits in.

Battery indicator installed at the bottom of case

Battery indicator and GT power wired to Battery cable and hot glued in place.
The indicator preforms better if connected direct to the battery thick wire rather than
the thin wires of the GT.

Battery pack installed

Cover closed

[PCE/TG-16|CD/SGX Discussion / PC engine LT2]

This looks pretty smart.

[Console Repair/Mod Center / PC Engine GT Screen mod]

Ok I now have a working circuit/mod for the GT with no wiring to the Grafix chip.

This works directly from the flat cable lcd connection of the GT.

RGB + HSync to composite converter. 5V power.

Schematic below.



2.4" display link. You can ask for the 5V version.

http://www.good-display.com/products_detail/&productId=186.html

I have bread boarded the circuit and there is some noise on the picture.
The adjustable cap does allow you to tweek this out to a point.
I have not tried a fixed cap on the xtal or upping the RGB 0.1uf caps to reduce it.
This may help.

Schottky diode on the 5V is optional but advisable as Ive popped the fuse a couple of times connecting the flat cable incorrectly

I also used the original back light circuit board to wire the circuit to do the test circuit so you could do this.
Just remove all the components prior.

Overall the colours are good and the res on the 2.4" is 480 x 234 and preforms really well.
Not tried the 3.5"

There is another version which is a  AD725 IC and has a Luma trap circuit you can add which may preform better but I've not the time to do this.

Made some boards in the end. Tested and working.

OG: https://i.imgur.com/8uR229H.png

SETUP

Allow the unit to warm up . Play system for 5 mins.
Fine adjust xtal pot to tweek out slight jitter on edges of red.

MODS

75r resistors on RGB input not needed.

For 7v - 12v lcd's tapping the switched DC input to power lcd points.

OG: https://i.imgur.com/b5ZG8xT.png

The 5v supply onto the ribbon cable needs a mod.
Removal of Q507 and shorting fixed 5V to ribbon connection is shown below.
Note wire does not connect to pads located either side of the wire. Only the central one.

OG: https://i.imgur.com/1ocVDh4.png

If you need help or questions just PM me.

If you want PCB's with or without components PM me.

Gerbers are also ready so PM me with your email address if you want a copy.

I have 9 completed pcb's for sale and when they are gone thats all I'm going to do.
There will be some bare boards leftover so again PM me if you want some.

I will pass my gerbers onto Keith Courage who may make some for the future.

Enjoy.

[PCE/TG-16|CD/SGX Discussion / PC Engine Duo card]

Is this a copy?

I did not notice that the potting was the full length of the card. Are they all like that?

http://www.ebay.com/itm/NEC-PC-ENGINE-Hu-card-ARCADE-CARD-DUO-card-only-Japan-for-DUO-/361603324353?hash=item54313cd9c1:g:XCAAAOSwPc9W1cYx

[Console Repair/Mod Center / Multitap]

Anyone know if any of the variants of the multitaps have standard TTL IC's in them?

e.g 3way and 2way versions.

The five way one I have has what looks like either an asic or pld etc so no go here.

Any info on the above would be appreciated Thanks

[PCE/TG-16|CD/SGX Discussion / Snespad2PCE Raffle]

Ok I'm going to raffle one pcb with all components, just needs the PC engine cable side added.

This pcb converts a Snes pad to either a 2way or 6way PCE pad selected by a switch.
The 2way has I and II (Y & B) mirrored with auto fire on X & A.
Select is also mapped to the right shoulder button.

It's not high tech and just totally made up of TTL IC's using a 6way pad circuit.

Have a couple of errors on the pcb so not perfect.

Should have placed a mini 8pin dim pcb socket on the board but may do it another day.
Hopefully someone may have a CPU version done by that time.

OK 1 week to for the raffle.

[Console Repair/Mod Center / SNES Pad to PC engine adaptor]

I have a working circuit for a SNES Pad to 2/6 Avenue style pad converter.
Would like some input of what keys to set to the SNES buttons.
Obvious ones are set below. Missing ones with ?

This is going to be set once the pcb is made.

PCE : SNES
Run     : Start
Select  : Select
Up       : Up
Down   : Down
Left      : Left
Right    : Right
?          : Y
?          : B
?          : X
?          : A
?          : Left Shoulder button
?          : Right Shoulder button

Will have switches for
2/6 pad
auto fire for I
auto fire for II
Slow mo

If the adaptors auto fire are switched off any snes pad having auto fire switches should work.
Dont have one to test.

Still have to source switches and design the pcb.

Will make a bunch up for sale to all at PCenginefx and schematic etc will be released.

[Console Repair/Mod Center / Duo V's Duo-R Sound]

Has anybody else noticed the sound difference between a Duo-R and Duo? I've had a Duo-R for some time and just noticed how bright the sound is on a Duo. The two differ so much I'm considering switching to the Duo. The Duo-R sounds muffled and too much low end.

[PCE/TG-16|CD/SGX Discussion / Production qty's]

[Console Repair/Mod Center / Turbo Everdrive IR remote control reset]

I found that getting up off my arse every time I wanted to change a game on the Turbo Everdrive was in need of a solution.
Nope not a extra long stick but an IR remote controlled reset.

I bought one of these remotes online really cheap.



I programmed it using the routines from this web site.

https://arduino-info.wikispaces.com/IR-RemoteControl

Modiying it in two sections. I had kept all the other sections of code for testing on serial.

void setup()   /*----( SETUP: RUNS ONCE )----*/
{
  Serial.begin(9600);
  Serial.println("IR Receiver Raw Data + Button Decode Test");
  irrecv.enableIRIn(); // Start the receiver
  pinMode(2,OUTPUT);
  digitalWrite(2,HIGH);
}/*--(end setup )---*/

and changed the case routine on several buttons.
Only one shown below.
This adds a 600ms pulse to reset the Everdrive.

case 0xFF22DD: 
    digitalWrite(2,LOW);
    Serial.println(" PREV           ");
    delay(600);
     digitalWrite(2,HIGH);
    break;

Wire the IR sensor to the Arduino Mini and Turbo Everdrive using the colour coded diagrams below.

Turbo everdrive pinout


IR sensor pinout


Arduino mini 168 pinout

[Console Repair/Mod Center / Fram Duo Mod]

This is a Fram mod rather than a Sram mod that WilyKat is doing.
The Fram is more expensive than the Sram version but....
Unlike Sram does not need a large storage cap to hold memory.
So no loss of data for years and years and years....

No battery in the Tennokoe Bank.

IC is a Cypress FM18W08.

It's a FRAM with a similar pinout.


_{HQ: https://i.imgur.com/8SKkna1.png}

Formatted Ram OK.
Have just tried Soldier blade and save is in the bank.


_{HQ: https://i.imgur.com/YtQFCa4.png}

Just ordered some switches which are Hartman PT65503 16way hex.

This a rotary switch that will have pullup resistors giving an extra 16 banks of data.

Will wire up the switch when it arrives and post to all a wiring diagram.

This will of course work with WilyKats great piece of work on the next thread.
I will probably upgrade mine to his switching circuit when he's finished it.

[PCE/TG-16|CD/SGX Discussion / Sealed games]

I cant believe I've just done this but I've Just bought three sealed hucard Games.
I've only done this once in the 26 years of collecting PC engine games.
That was when I bought Soldierblade when it came out and I opened it straight away and played it.

I've bought and sold my collections three times now and thought the bug had gone
and then this year It hit me once again.
I've bought consoles I've never had and that's great.

But never sealed copies.

What do I do when I get them?

[PCE/TG-16|CD/SGX Discussion / Yahoo auction]

Just had a costly confusing time on Noppin, bidding on the Yahoo Japanese auction.

Caught out on auto extension?

I know I wanted it but how did they get the bid up to the point where my bid still held.

Then there's the Noppin fee.
