Mupen64Plus Plugin Parameters
From Mupen64Plus Wiki
Plugin Parameters
These are standard parameters which are used by the Mupen64Plus plugins. The behavior of the plugin library when these parameters are changed while the emulator is running is not defined here. Some plugins will load the parameters when starting and store internal copies of the parameters for use during emulation. Other plugins may read the value of the parameters while running.

| ForcePolygonOffset | M64TYPE_BOOL | If true, use polygon offset values specified below (default=False).

Ignored if ForcePolygonOffset is False, and typically only relevant for mobile/embedded platforms. This value is typically equal to PolygonOffsetUnits, and is found through trial and error. Mario's shadow in Super Mario 64 is a good test case when tuning this value. If the shadow flickers, use a larger magnitude for the float settings. Do not use a larger value than necessary to eliminate artifacts. As a guideline, typical values for mobile chipsets circa 2012-2014 are positive or negative values in the range 0.001 to 2. |
| PolygonOffsetUnits | M64TYPE_FLOAT | Is multiplied by an implementation-specific value to create a constant depth offset. Ignored if ForcePolygonOffset is False, and typically only relevant for mobile/embedded platforms. This value is typically equal to PolygonOffsetFactor, and is found through trial and error. Mario's shadow in Super Mario 64 is a good test case when tuning this value. If the shadow flickers, use a larger magnitude for the float settings. Do not use a larger value than necessary to eliminate artifacts. As a guideline, typical values for mobile chipsets circa 2012-2014 are positive or negative values in the range 0.001 to 2. |
Input-SDL
The Mupen64Plus-Input-SDL plugin uses a separate config section for each simulated N64 controller. The sections are named: Input-SDL-Control1, Input-SDL-Control2, Input-SDL-Control3, and Input-SDL-Control4. The 4 sections all contain the same parameters.
