My DS2 Pad Tests

[venice1200]

Hi @vossstef,
I build my DS2 Adapter for the Spare Pin Header of the MiSTeryNano Midi Shield today and did some tests with a modified Core v1.5 to be able to use the Spare Header Pins.

Adapter for Spare Pin Header J8 (SPH) on the MiSTeryNano Shield and the Playstation Dualshock 2 Controller

Here are my Findings using the DS2 with my Adapter.

DS2 Pad Analog Mode (LED) On or Off (doesn't matter)
Testing with H.E.R.O two Button Version (NTSC)
Direction Buttons OK
Left Analog Stick not working
Select & Start Ok
Circle/A = Button 1 (HERO Fire)
Cross/B = Right Direction (!)
After pressing the Button the Direction Buttons are no longer working (Paddle Mode?)
I need to press Circle/A to get the Direction Buttons working again
Traingle/X = Left Direction (!)
After pressing the Button the Direction Buttons are no longer working (Paddle Mode?)
I need to press Circle/A to get the Direction Buttons working again
Square/Y = Button 2 (HERO Bomb)
Shoulder Buttons no function
Same with HERO (OneButton) PAL Version

DS2 Pad Analog Mode On
Testing Super Breakout
Select & Start Ok
Slider Game Direction with Left Analog Stick (Left/Right) Ok
Circle/A = After pressing the Button the left Analog Stick is no longer working
I need to press Cross/B or Triangle/X or Square/Y to get the left Analog Stick working again
Cross/B = Button 1 (Start Ball)
Triangle/X = no function
Square/Y = no function

Testing Video Olympics
Game Direction with Left Analog Stick (Up/Down) Ok
Need to invert Paddle direction

If you press the wrong button the Pad stops responding which is inconvenient (the same happens with an USB Pad).
Maybe a two button combination will be better for paddle activation/deactivation.

The first Button is Circle in Joystick Mode and Cross in Paddle Mode?

Btw, Mouse 🖱️ as Paddle works fine 👍

Happy X-Mas 🎄

@venice1200,
if you don't mind would like to add your cable build instructions incl picture for other users. Is that o.k ?

Many thanks for your valuable feedback and would like to improve the design over the next weeks.

I pretty much copied the mister core but let certain input switchmode function (joy, paddle, mouse) for the time being away and of course the key mapping might be different...

Feel free to have a look at the readme.md https://github.com/MiSTer-devel/Atari2600_MiSTer
and https://github.com/MiSTer-devel/Atari7800_MiSTer to understand what i ported and about game control.

Initially i thought that porting of that small core is simple but ended up with a rather long lasting exhausting excersise and A7800 ROM autodetect and the video stabilizer blocks finally made the core working. Game Input control was right from the beginning a nightmare...

I am happy to help.

You can use anything I post for the documentation.

I used your code and added some modified files for supporting the Spare Pin Header for DS2.
If you like I can fork your repo, add my changes and send a pull request.

Nothing of the original work is changed.

Hi @venice1200,
i need to include the Shield Board pinheader as a selectable game input option in all the designs. Meaning present 'Joystick to DIP' in use and alternatively Shield pinheader for DS2. Would be great if you could create an extra jumper cable build instruction page (.md and graphics as .svg inkscape) with all needed deatils how to construct and purchase the needed parts. Also an edited TN20k drawing where new pinheader signals are shows will help too. I was yesterday evening browsing aliexpress to find your jumper cable but didn't found exact match but many parts that could be re-used to construct such a thing.

[venice1200]

Let me see what I can do for you (us).

I use an old (and maybe defective) Playstation Controller extension cable.
I was in luck as the female connector and the connected part of the cable was Ok.

I crimped the Pins onto the cables. Beta test Ok.

But I am waiting for female connector parts from Ali and I am going to create a PCB for this connector with a 10 Pin header to use 10-Pin flat cables and connectors for an easy 1:1 connection to the Pin Header of the MiSTery Nano Board.

I will provide my cst later.

Aloha

.cst will use to update OSD and core that you immediately have a new input selection apart from further needed finetuning in the controller keymaps.
Big Thanks !

[venice1200]

.cst attached.

First try..

Hi @venice1200 ,
PCB looks Great !

You will find the design changes here: https://github.com/vossstef/A2600Nano/tree/ds2_4_misteryboard20k
Pls. select in existing OSD "DS2 #2 Joy" as input port for the pinheader. I didn't tested as i don't have a cable yet but ordered a Y-Adapter from Ali that i could disintegrate.

[venice1200]

That works 👍
With DS2 #2 i get my DS2 Pad working in the same way as in my previuos test above.

If the femal connectors arrive I will double check the PCB and order some of them.

Btw, is is now possible to use two DS2 Controller with the MiSTery Board?

No.1 using the original Pins
No.2 using the Spare Header

Yes both interfaces can be active at the same time. There is for the Joy to DIP interface no header but you could solder adhoc somw wires. Good point and i will meantion that in the readme too. Thought that coud could add via pull an extra document with the build instructions linked from readme.
