Topic:
I tried diffent emulator for N64 and lr-mupen64plus-next work best for me (no sound glitch, no freezing). I dont care if its not HD.
However on rogue squadron I'm unable to setup the controller correctly. The C-down and C-Left doesn't work. I tried to setup different combination for configuring the controller, none is working. I also tried to configure it in retroarch.cfg . I can change the map of different button, but I cannot assign C-down and C-Left. (Which are 0 and 3 on JSTEST).

Question 1:
Is mupen64plus.cfg and InputAutoCfg.ini are used by lr-mupen64plus-next ?

Question 2:
Is there an equivalent to lr-mupen64plus-next that doesn't use retroarch?

Question 3:
How to setup properly my n64 controller?

@francis2019 for lr- cores just hit select + X then map the controls from that menu, they don't use those config files.

Mupen64plus is the standalone non lr equivalent, that uses those config files you mention.

When you say N64 controller, you mean the new switch online one? I don't know if that controller works yet

@retropieuser555
Thanks for the response.
I need to do select + X when the emulator is running?
or in emulation station?

I was finally able to set it up.
I configure the control the best that I can in Emustation.
With HotKey is the Cpad UP
And then I put this configuration in Retroarch.cfg in the N64 folder.

Settings made here will only override settings in the global retroarch.cfg if placed above the #include line
