What it is Filled
In video gaming, a multitap is a console-specific adapter that connects multiple controllers through a console controller port, allowing compatible software to support additional simultaneous players.
In scope
- Console-facing connection and downstream controller ports
- Controller signalling, selection and player-slot mapping
- Compatibility with consoles, controllers and individual games
- Power requirements, operating modes and connection procedures
- Faults affecting controller detection or simultaneous play
Out of scope
- Electrical power strips or multi-outlet adapters also called multitaps
- Multi-tap text entry on telephone keypads
- Game controllers and their internal input mechanisms
- Console hardware beyond the multitap interface
- Game rules, multiplayer design and network matchmaking
Why it exists Filled
Enable an AI agent to recognise a video-game controller multitap, assess its compatibility and condition, and determine how it can support additional players.
Distinguishing features Filled
- Provides multiple downstream controller connections through a shared console-facing controller interface.
- Keeps controller inputs distinguishable through a supported signalling or selection mechanism; connector multiplication alone does not establish multitap functionality.
- Expands locally addressable controller connections rather than providing network sessions or online player capacity.
- Requires compatibility to be assessed at the console, controller and game levels; matching plugs alone are insufficient.
- Is distinguished from a generic USB hub by evidence of its role in the console's supported controller-expansion arrangement.
What robots and AI may and may not do Filled
Must not
- Describe an adapter as compatible with a console or game without evidence.
- Sell or describe a third-party or reproduction adapter as original.
- Recommend modifying old adapters in ways that risk damaging consoles.
Only with a human decision
- Selling or trading collectible hardware on someone's behalf.
May
- Identify a multitap and the console it was made for.
- Explain which games support it and how many players it allows.
Moral aspects Filled
- Shared play brings people together; accessible hardware matters for disabled players.
- Collectors can be misled by false claims of authenticity.
Who is affected
- Players
- Collectors
- Buyers
Owners Filled
Steward
The person who owns the adapter.
