# ------------ H - HERE IT IS - GLOBAL EMULATOR CONFIGURATION ------------ #
## The global value will be used for all emulators, except if the value
## is redefined in the emulator
## Set game resolution for emulators
## select your mode from the command : tvservice -m [MODE]
## CEA 5 HDMI : 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced
## CEA 4 HDMI : 1280x720 @ 60Hz 16:9, clock:74MHz progressive
## use 'default' for using the default resolution
## (string)

## (none, retro, scanlines)

## Set retroarch input driver (auto, udev, sdl2)
## If you don't have issues with your controllers, let auto

## If you do not want recalboxOS to generate the configuration for all emulators (string)
;global.configfile=/path/to/my/configfile.cfg
# ------------ I - EMULATORS CHOICES ----------- #
## You can override the global configuration here
## Here is the snes example
;snes.videomode=CEA 4 HDMI
snes.core=snes9x_next
;snes.shaders=/recalbox/share/shaders/shaders_glsl/mysnesshader.gplsp
;snes.ratio=16/9
;snes.smooth=0
;snes.rewind=1
;snes.autosave=0
;snes.emulator=libretro
;snes.integerscale=0
## If you do not want recalboxOS to generate the configuration for the emulator :
;snes.configfile=/path/to/my/configfile.cfg
;snes.smooth=0
;snes.rewind=1
;snes.autosave=0
;snes.emulator=libretro
;snes.integerscale=0
## If you do not want recalboxOS to generate the configuration for the emulator :
;snes.configfile=/path/to/my/configfile.cfg
## Default cores for RPi3
snes.core=snes9x_next
gba.core=mgba
mame.core=mame078
nes.core=fceunext
## NeoGeo emulator
## You can use pifba or a libretro core (fba2x,libretro)
neogeo.emulator=libretro
## If you set libretro as neogeo.emulator, the line below sets the retroarch core (fba,imame4all)
neogeo.core=fba
## N64 emulator is configured to display a screen with a 640x480 resolution (native n64 resolution)
## So you must use one of these video modes (DMT 4 HDMI,CEA 1 HDMI).
## If your screen is not compatible with one of these video modes, please check the recalbox's wiki.
n64.videomode=DMT 4 HDMI
## If you are using a CRT screen, please change the setting above with this one :
# n64.videomode=default
