Playing in linked mode with only one disc
Note: Sony does not recommend removing a spinning
disc from the Playstation.
Connect two Playstations with the linkcable, and power on
both systems. Begin Doom on Playstation 1. Select Deathmatch or
a cooperative game. Playstation 1 should try to connect to Playstation
2. Wait a few seconds, remove the disc from the Playstation 1,
and start the game on Playstation 2. Enter all selections identically
to Playstation 1 and begin playing.
The game will hang from time to time. At these points, swap the
disc to the other Playstation after waiting a few seconds before
removing the disc.
