I bought 3 n64 controllers (SWITCH CO.,LTD. Controller (Dinput)) which I somehow cant't get use my settings from mupen64plus.cfg.
When I set n64.configfile=dummy in recalbox.conf the controllers won't work at all, otherwise the default recalbox mapping is used. With n64.configfile=dummy after starting a n64 game a box is shown which tells me the controller is not configured.
I noticed that neither mupen64plus.conf nor InputAutoCfg.ini are ever updated. Actually InputAutoCfg.ini didn't even exist (I created it on my own just for testing)
Accoring some thread I deleted mupen64/input.xml, but it was not re-created as well.
I'm quite sure my mappings are correct, because I crosschecked with a mupen64plus.conf on my computer where the controllers work fine.
Board Model: raspberry pi 4b
Sd Card: SanDisk Extreme 128 GB
Controller: miadore Retro 64-Bit (SWITCH CO.,LTD. Controller (Dinput))
Emulators: tested all 3
I found a thread where there same problem was reported, but only after the original problem was already solved:
