Virtual Pinball is packed with unique terms that might seem puzzling at first. Consider this your secret decoder ring to understand the lingo and get the most out of your experience.

AltSound enables alternate sound sample support for ROM-based tables in Visual Pinball. Support is provided by the libaltsound library that is built directly into VPinMame. This lets tables play different sound samples than the default ones, adding audio variety and realism.

From the b2s-backglass wiki:
"When a pinball table is run through Visual Pinball (VPX), the VBS script (included in the table) calls the B2S server... and displays the backglass specifically made for the selected pinball table. The backglass file (tablename.directb2s) is an XML file with images and instructions on when to display certain smaller images that simulate lamps behind the backglass. The trigger can come either from a pinball ROM via VPinMame or directly from commands in the table VB script."

• On Windows, B2S Server is a separate plugin (more info and downloads).
• On Linux, macOS, and mobile standalone builds, it’s included automatically.

DOF is a software framework that lets you control external hardware devices (like LEDs, motors, or solenoids) from Visual Pinball. It works through a controller connected to your PC running VPX. For example, it can drive addressable LEDs via a Teensy or ESP32 microcontroller or activate relays for motors.

Use the DOF Config Tool to customize your hardware setup.

Fleep is a developer who recorded multiple real pinball machine sound samples — things like ball rolling, flippers, slingshots, and bumpers. Multiple versions of each sound are randomized during gameplay for a natural, realistic audio experience. Fleep also added positional audio support, enabling Surround Sound Feedback (SSF).

A table configuration that shows the playfield, DMD (Dot Matrix Display), and Backglass all together on a single screen. Great for setups with only one monitor or device.

nFozzy is a developer who created a physics model widely considered the best starting point for Visual Pinball tables. This model powers VPW’s default physics and closely simulates real pinball ball movement and interactions.

Serum is an open-source colorization format for pinball ROMs. It’s the only colorization format supported by the Standalone version of Visual Pinball.

SSF is a tactile feedback system that simulates physical sensations in your pinball cabinet using bass shakers and exciters. It works alongside or as an alternative to mechanical feedback like motors and solenoids.

By using specialized audio hardware (7.1 channel sound cards, bass shakers, exciters, amplifiers), SSF can mimic the feel of a ball rolling, flipper hits, and other table effects through vibration.

VPX is the shorthand for Visual Pinball Version 10, the modern version of the pinball simulator. See the VPX GitHub repository for the latest source and releases.

VPX supports Virtual Reality gameplay! Originally maintained as a separate build, VR is now integrated into VPX (since version 10.8). You can play any VPX table in VR, though tables optimized for VR (with a “VR Room”) will give a better experience, including backglass, cabinet, and DMD display.

VR mode is also useful on mobile devices (iOS, iPad, Android) to combine multiple display elements on one screen.
