8BitDo M30 2.4g button mapping is off after March 23rd update

[FoggyHedgehog]

Hi all,

I noticed that I can no longer map the correct buttons on my 8BitDo M30 2.4g controller.
This is only happening for the Saturn core and the problem does not occur if I for instance map the buttons to a keyboard. I also used a second 8BitDo M30 2.4g controller only to have the same issue.

More specifically, the down button on the D-pad is no longer mapped while many other buttons are wrongly mapped and duplicated.

Out of curiosity, has anyone else had this issue? or is this a fringe case/my mistake somewhere

Thanks in advance

Do you mean the version for the Mega Drvie Mini, with an USB Dongle? This one works fine, i use the white Edition without any issues. Have you tried to delete the Saturn Core config files (in the media/fat/config/ folder) and start to configure again?

You could also try the latest beta core from 09.04.2024, which has a lot of improvements. It's the single Ram version.

Indeed I should have been more clear. I'm using the (white) Mega Drive Mini with a USB Dongle on the most recent stable core.
Interestingly, both deleting the config files and using the provided (thanks for that) unstable core did not change anything.

I was also wrong about the 'down' button not being mapped, it actually maps to the 'up' button. The left/right D-pad buttons are mapped correctly.

It's such an odd phenomenon, I'll likely wipe the whole SD and start again to see if it changes anything.

Thanks again

** a Retro-bit N64 Tribute is working well, so I'll use that for now **

You can try to register the Pad again in the MiSTer main menu, maybe the mappins are messed up on this level.

You're aware that you can change the M30s behavior by certain button combinations? Probably worth giving it a shot / switching to xinput.

Hi all!

Thanks for all the great suggestions! After trying re-registering in the main menu and changing the controller behaviour with different button combinations, I simply wiped the Mister config folder. This in the end did the trick. I still don't know what specifically caused it and why remapping the buttons had no effect, but at least now everything is under control again.

Thanks again for all the feedback and patience.

i've the 8BitDo M30 2.4g too and can't map the L und R buttons on the controller. anyone an idea? Saturn core is V240628.

[FoggyHedgehog]

The only thing that worked for me was wiping the config folder, did you try that already?

[heinzgruber]

you mean deleting the whole config folder from MiSter with all the cfg files? i'm afraid to do that because there are some speical configurations for ao468 and amiga.

[FoggyHedgehog]

you can back up the folder before you wipe it, that way you can at least check if it makes a difference for the button mapping

strange is; i've remapped the controller for MiSTer menu and left out the L and R buttons. But now the R button is mapped for OK in MiSTer menu. I think thats why this button is cannot be mapped in Saturn core. Is there a way to reset the controller config?
