Issue description

Games that should support DualShock do not properly respond to analogue input with the DualShock emulation.

To set context, I moved from an RG552 (running r231 ab206b0) and Vagrant Story runs perfectly with DualShock controls/emulation.

I have been extremely particular in making sure that all settings, bios, md5 checks etc are absolutely identical between both versions of the core running through Retroarch.

Vagrant Story works fine on my RG552, but on my RG556, I can only move up and down (forward and backward… and sometimes to the right) when using the analogue stick.

I have tested my RG556’s hardware and it’s working fine in other cores. However all games that support DualShock on PSX with the PCSX-ReARMed Core are behaving the same way.

Please can someone help?

Step-by-step reproduction and logs

No response

Please let me know if there is anything I can add. I’m not sure how to advise on replicating the problem as it seems to present itself as soon as I load and play any game.

I've tried it on stock RetroArch on PC and it works correctly. What frontend is the RG556 using?

[raelharris]

Hi notaz, The RG556 runs Android 13 and Retroarch is just an app installed on the device. Does that answer your question? Regards,

There are various things that can run libretro cores (not just Retroarch) so I was trying to ask if it's Retroarch or something else.

Anyway try changing Core Options -> Input -> Analog Axis Bounds to Square and see if that helps. If not, please run the following homebrew through the emulator:

and report the maximum x/y ranges you can get using your controller.

Thanks,How do I run that homebrew through Retroarch? I’m only familiar with running homebrew through command line inputs like terminal.Thanks,Rael HarrisOn Dec 28, 2024, at 15:59, notaz ***@***.***> wrote: There are various things that can run libretro cores (not just Retroarch) so I was trying to ask if it's Retroarch or something else.

Same as any psx game, there is a cue/bin cd image included.

Hi Notaz,

Sorry it's taken me so long in getting back to you. The holidays and work had me busier than I'd hoped... My results using the app are:

Upper Left: (-128,-128)
Upper Right: (127,-128)
Lower Left: (-128,127)
Lower Right: (127,125)

This is encouraging because it looks like I was getting proper DualShock response while in the PCSX-ReArmed Core! However, I noticed that when I reached a certain threshold, D-Pad input registered, is that normal? I have attached a screenshot.

[notaz]

No that's not supposed to happen, probably something in your RetroArch config as the core itself doesn't do any such mapping.

[raelharris]

Thanks Notaz,

Do you know where I could go to from here to try and lock down who to go to, in order to work out where that setting might be?

[notaz]

Don't know about the Android version but on PC there is "Main Menu > Configuration File > Reset to Defaults", you could also reinstall I guess. I'm not involved with RetroArch and just maintain the core so don't know much about it.
