| Vector resolution multiplier (Restart core) |
Attempts to create a higher quality emulation of vector display hardware by upscaling the emulated display to a higher resolution. mame2003-plus_vector_resolution = "1024x768|640x480|1280x960|1440x1080|1600x1200|original" |
| Vector antialiasing |
Enables or disables the anti-aliasing for vector games. mame2003-plus_vector_antialias = "enabled|disabled" |
| Vector beam width |
Sets the emulated width of the vector beam in pixels. This setting is only effective when anti-aliasing is enabled. mame2003-plus_vector_beam_width = "2|1|1.2|1.4|1.6|1.8|2.5|3|4|5|6|7|8|9|10|11|12" |

Emulates the variable intensity of vector display hardware. mame2003-plus_vector_intensity = "1.5|0.5|1|2|2.5|3" |
| DCS Speedhack |
Advanced feature: changing from the default is not recommended in most cases. Use so-called "speed hacks" to improve the performance of DCS sound hardware. mame2003-plus_dcs_speedhack = "enabled|disabled" |
| Locate system files within a subfolder |
For historical reasons, MAME 2003-Plus reads system files within a subfolder named mame2003-plus even though this is not part of the libretro API. mame2003-plus_core_sys_subfolder = "enabled|disabled" |
| Locate save files within a subfolder |
For historical reasons, MAME 2003-Plus saves files within a subfolder named mame2003-plus even though this is not part of the libretro API. mame2003-plus_core_save_subfolder = "enabled|disabled" |
| TATE Mode |
From the Japanese 縦 (ta-te) meaning "vertical", TATE Mode renders vertical games lengthwise along the display. This mode is intended for use with rotating monitors and portable devices that can make the full use of their viewable area for games which used vertical monitors. mame2003-plus_tate_mode = "disabled|enabled" |
| Brightness |
Simple brightness adjustment. mame2003-plus_brightness = "1.0|0.2|0.3|0.4|0.5|0.6|0.7|0.8|0.9|1.1|1.2|1.3|1.4|1.5|1.6|1.7|1.8|1.9|2.0" |

| Frameskip |
Advanced feature: changing from the default is not recommended in most cases. mame2003-plus_frameskip = "0|1|2|3|4|5" |

| Input interface |
Advanced feature: changing from the default is not recommended in most cases. retropad, the default option, processes input via the libretro retropad abstraction, including from any keyboard which are bound to the retropad. The keyboard setting only sends keyboard input directly to the core, ignoring the retropad. The simultaneous setting sends inputs both ways at the same time and is not recommended. This setting exists for historical reasons. mame2003-plus_input_interface = "retropad|keyboard|simultaneous" |
| Legacy Remapping |

| Center joystick axis for digital controls |
Emulates the center position of an analog joystick to allow digital joysticks to play analog based games. This is only applied when the AD Stick type is used. mame2003-plus_digital_joy_centering = "enabled|disabled" |
