Hello,
Triggering “input_b_btn” on any kind of controller trigger a reset on my games. I’m using autoconfig and everything seems fine on other cores, so i don’t think it is an issue with my config.
Skeleton config file for RetroArch
Save all save files (*.srm) to this directory. This includes related files like .bsv, .rtc, .psrm, etc …
This will be overridden by explicit command line options.
savefile_directory = “/media/EMU_DISK/retroarch/savefiles/”
Save all save states (*.state) to this directory.
This will be overridden by explicit command line options.

If set to a directory, the content history playlist will be saved
to this directory.

loadable assets, etc.
assets_directory = “/usr/share/retroarch/assets/”
Sets start directory for menu config browser.
rgui_config_directory = “~/.config/retroarch/”
Show startup screen in menu.

video_fullscreen_y = 0
Start in fullscreen. Can be changed at runtime.
video_fullscreen = true
If fullscreen, prefer using a windowed fullscreen mode.

suggests RetroArch to use that particular monitor.
video_monitor_index = 0
Forcibly disable composition. Only works in Windows Vista/7 for now.
video_disable_composition = false

video_hard_sync_frames = 0
Sets how many milliseconds to delay after VSync before running the core.
Can reduce latency at cost of higher risk of stuttering.
Maximum is 15.
video_frame_delay = 0
Inserts a black frame inbetween frames.
Useful for 120 Hz monitors who want to play 60 Hz material with eliminated ghosting.
video_refresh_rate should still be configured as if it is a 60 Hz monitor (divide refresh rate by 2).
video_black_frame_insertion = false
Use threaded video driver. Using this might improve performance at possible cost of latency and more video stuttering.
video_threaded = false
Use a shared context for HW rendered libretro cores.
Avoids having to assume HW state changes inbetween frames.

Smoothens picture with bilinear filtering. Should be disabled if using pixel shaders.
video_smooth = true
Forces rendering area to stay equal to content aspect ratio or as defined in video_aspect_ratio.
video_force_aspect = true

The base size depends on system-reported geometry and aspect ratio.
If video_force_aspect is not set, X/Y will be integer scaled independently.
video_scale_integer = false

If this is not set, aspect ratio is assumed to be automatic.
Behavior then is defined by video_aspect_ratio_auto.
video_aspect_ratio =
aspect_ratio_index = “21”
If this is true and video_aspect_ratio is not set,
aspect ratio is decided by libretro implementation.
If this is false, 1:1 PAR will always be assumed if video_aspect_ratio is not set.
video_aspect_ratio_auto = false

video_message_color = ffffff
Video refresh rate of your monitor.
Used to calculate a suitable audio input rate.
video_refresh_rate = 59.95
Allows libretro cores to set rotation modes.
Setting this to false will honor, but ignore this request.
This is useful for vertically oriented content where one manually rotates the monitor.
video_allow_rotate = true
Forces a certain rotation of the screen.
The rotation is added to rotations which the libretro core sets (see video_allow_rotate).
The angle is <value> * 90 degrees counter-clockwise.
video_rotation = 0

audio_resampler =
Audio driver backend. Depending on configuration possible candidates are: alsa, pulse, oss, jack, rsound, roar, openal, sdl, xaudio.
audio_driver =
Override the default audio device the audio_driver uses. This is driver dependant. E.g. ALSA wants a PCM device, OSS wants a path (e.g. /dev/dsp), Jack wants portnames (e.g. system:playback1,system:playback_2), and so on …
audio_device =

If a joypad is plugged in, that joypad will be autoconfigured if a config file
corresponding to that joypad is present in joypad_autoconfig_dir.
Input binds which are made explicit (input_playerN_*_btn/axis) will take priority over autoconfigs.
Autoconfigs can be created with retroarch-joyconfig, manually, or with a frontend.
Requires input_autodetect_enable to be enabled.
joypad_autoconfig_dir = “~/.config/retroarch/autoconfig/”

rather than relying on a default.
input_player1_a = x
input_player1_b = z
input_player1_y = a

input_player1_left_axis =
input_player1_right_axis =
input_player1_up_axis =
input_player1_down_axis =
Holding the turbo while pressing another button will let the button enter a turbo mode
where the button state is modulated with a periodic signal.
The modulation stops when the button itself (not turbo button) is released.
input_player1_turbo =
Describes the period and how long of that period a turbo-enabled button should behave.
Numbers are described in frames.
input_turbo_period = 6

input_netplay_flip_players = i
Hold for slowmotion.
input_slowmotion = e
Enable other hotkeys.
If this hotkey is bound to either keyboard, joybutton or joyaxis,
all other hotkeys will be disabled unless this hotkey is also held at the same time.
This is useful for RETRO_KEYBOARD centric implementations
which query a large area of the keyboard, where it is not desirable
that hotkeys get in the way.
Alternatively, all hotkeys for keyboard could be disabled by the user.
input_enable_hotkey_btn =
input_enable_hotkey = “shift”

Rewinding buffer size in megabytes. Bigger rewinding buffer means you can rewind longer.
The buffer should be approx. 20MB per minute of buffer time.

Path to cheat database directory.
cheat_database_path = “/usr/share/libretro/cheats/”

video_gpu_screenshot = true
Block SRAM from being overwritten when loading save states.
Might potentially lead to buggy games.
block_sram_overwrite = false

it is saved.

slowmotion_ratio = 3.0
The maximum rate at which content will be run when using fast forward. (E.g. 5.0 for 60 fps content => 300 fps cap).
RetroArch will go to sleep to ensure that the maximum rate will not be exceeded.
Do not rely on this cap to be perfectly accurate.
fastforward_ratio = 1.0
Setting this to false equals no FPS cap and will override the fastforward_ratio value.
fastforward_ratio_throttle_enable = false
Enable stdin/network command interface.
