Crash/Freeze when assigning controller input

Hi,

I want to use a gamepad for the emulator and the program seems to recognise it:
"Found 1 joysticks
Joystick 0 HORI CO.,LTD HORIPAD S
Axes: 4
Buttons: 14
Trackballs: 0
Hats: 1
"
When I start a game normally, It detects the stick for movement but the other buttons are mapped all over the place.
When I want to remap them, the program freezes:
"Device: 0; Button: 2"
These are its last words in the terminal. It happened when I wanted to map the A button to the A input.

I'm using Ubuntu 18.04

Idk how dead this forum is, but it's my only hope.

Re: Crash/Freeze when assigning controller input

Ok I didn't know what it was supposed to be. "RetroArch is a frontend for emulators, game engines and media players."
So I installed it and now the controller does work but an old problem is back: The game runs SUPER slow as if in slowmo. Earlier I started desmume with "--cpu-mode=1" and this sped the game up to normal speed.
But I don't know how to do this via RetroArch.
Tried synching the GPU with the "Hard GPU Synch" setting in the latency settings but that didn't change anything.

Re: Crash/Freeze when assigning controller input

Re: Crash/Freeze when assigning controller input

Terminal says I'm alreay in CPU MODE: JIT when I launch the game.
But I can't find the core options anywhere

Re: Crash/Freeze when assigning controller input

this isn't retroarch support; ask the internet how to use it.
if the terminal already says jit then i guess there's not much else to do though. there are other emulation options in desmume which affect the speed, most notably "advanced bus-level timing" but I doubt retroarch has that on by default.
ultimately you may have to use a computer that's not a toaster.

Re: Crash/Freeze when assigning controller input

Well it can't be my machine's fault if demume itself runs the game smoothly and it only goes slow with retroarch.
Thanks anyway. I probably just will use my desktop PC instead.

Re: Crash/Freeze when assigning controller input

yes, it can be your machine's fault: if its capabilities are only barely sufficient for running full speed in desmume, then any extra inefficiencies due to retroarch will become visible.
