Notes

  • Audio volume is converted from 0–100% linear to dB (RetroArch uses a -80 to 0 dB range).
  • Video driver options: gl, glcore, vulkan, d3d11, d3d12.
  • Menu driver options: ozone, xmb, rgui, glui.
  • Audio driver options: auto, alsa, pulse, sdl2, wasapi, dsound, coreaudio.
  • Input driver options: auto, udev, sdl2, x, dinput, xinput.
  • Use the Export to RetroArch button to write configuration directly to the detected RetroArch installation.

Notes

  • MAME uses a -32 to 0 dB volume scale. The generator converts from 0–100% linear.
  • The window setting is the inverse of fullscreen (0 = fullscreen, 1 = windowed).
  • Shader support maps to MAME’s gl_glsl OpenGL GLSL filter option.
