Linking To Other Handhelds
Most handheld systems can link to others of the same type via a cable that connects two or more handhelds, usually to a maximum of 4. This feature allows both multiplayer gaming and other uses such as item or data transfer between cartridges. The Atari Lynx supported connectivity for up to 17 units at once.
The Game Boy Color introduced wireless multiplayer to handhelds with its infrared port. The N-Gage introduced wireless connectivity via Bluetooth, allowing multiplayer games between handhelds with no cable. Wireless gaming was also a feature in the Nintendo DS and PSP, using the Wi-Fi standard.
