You are right. I looked at them again last night and came to the same conclusion: they make no sense.
Instead, I’ve used yours (thanks for sharing this!) and went testing. Unfortunately it had gotten rather late by then and the driver wouldn’t install properly (different kernel version). When I installed the right headers etc, my SD card was full (only 4Gb to experiment with).
To cut a long story short: it will take some more time for me to test the adapter.

Should it work, it can be used with many emulators I guess as UAE4ALL2 was the only problematic one so far. Now that you found out it works when it’s started manually, it’s a very good (temporary) workaround.
Hope Mame works with your adapter as well by the way, that is another emulator that I’d be using often. Problem is that ‘our’ joysticks only have one button and Mame games often use more..
I was thinking it would also be nice to be able to ‘break out’ the GPIO pins using the IDE cable ending in a contra IDE adapter and then have multiple adapters like the ones you have soldered for different controller types.

Thanks for this, great!

I looked at your ‘small project’ thread and noticed the numbering in your table ‘joystick connection matrix’ doesn’t match the numbering here: https://github.com/retropie/RetroPie-Setup/wiki/Db9_gpio_rpi

Is it because I haven’t slept much last night or is this wrong in any of these schemes? :)

Hi!

Awesome, nice finding! I have a feeling we’re getting there :)

Problem is that my self made adapter gets recongnized as a 6 axis, 8 button adaptor. Both joysticks connect to the same adapter and the adapter maps to js0. Using my device, there is no other option than to be able to manually configure/map controls or to have controls detected (like Vice does).

However..as I have a retro gaming evening planned for tomorrow with an old friend (we do that every now and then :) ), I’m thinking to quickly use your solution and use that for the time being. The main question I have: how did you go about manually installing the DB9 GPIO driver? Could you please guide me somewhat as I’m lacking time?

The other thing I need to find out is how to send audio over HDMI. Saw a thread about it and tried the solution but it didn’t work. Will try some more tonight.

Cheers!

Hi Flausch,

I read the topic you mentioned including your post. Great job.
For me it’s not clear either where to turn to so you’re right to ask where this should be addressed (on which level).
But say that Chips would address this someday soon, how would we need to get it incorporated into RetroPie? Any idea?
I haven’t been able to find a roadmap or release planning for RetroPie, you?

In the meanwhile I was fiddling a littlebit with joy2key. Have you ever looked at that?
It translates joystick events to keyboard events. That way, I was hoping I could simulate the right keys that UAE4ALL2 accepts when keyboard is configured as input method (but still…it wouldn’t give us simultaneous 2 players gameplay I’m affraid).

Hi Flausch,

Interesting topic.
I’m trying to achieve exactly the same: a 2 player Amiga/C64 gaming experience on the RPI (using Retropie).

I’ve once soldered a small device which accepts two 9-pin Amiga/C64 joysticks and connects to an old game port (25 pins?). Now that this port has become obsolete, I’ve bought a gameport to USB adapter from Ebay which works fine on Windows (WinUAE).
However, I haven’t managed to get it working on Emulationstation. I’m instead using a PS3 controller for that for the time being.
I’ve managed to get Vice working with the C64 jostick (by having it ‘learn’ the controls).
What I read about UAE4ALL2 however is that it has the controls pretty much hard coded, i.e. not configurable through a config file or whatever.
If that’s really the case, I’d need to wait for an improved version of UAE4ALL2 and Retropie of which I don’t know how long it would take.

So the solution you are looking into would be a good alternative.
I’ll look into this as well. Can you keep me posted on any findings please? Trying to get this to work asap :)

Regards,
Rinusch
