Power-Off Codes

From WebTV/MSN TV Wiki
Jump to navigation Jump to search

This page's purpose is to catalogue all known power off codes used with each revision of the WebTV/MSN TV product, their purposes, and how they can be triggered. This list is by no means complete or accurate, and we plan to continuously add more information we can gather as time goes by. If you have anything you'd like us to correct or add to this page, then shoot us an e-mail and we'll eventually add onto this if we consider your information legitimate enough.

Almost all information so far has been sourced from MattMan's page on known power off codes from his hacking site, with us at the moment merely adding in our own notes and information on previously-unknown power off codes for the MSNTV 2 (codes 8086 and 357).

First-Generation WebTV/MSN TV

To trigger power-off code, turn off unit and either press OPTIONS 3 times and then type out numeric code, or use the remote combo if applicable. The box lights should flash for a bit after successfully detecting the code.

Japanese Dreamcast

Power-off codes for WebTV for Dreamcast.

To activate, press the S3 key on the Dreamcast keyboard 3 times right as the splash screen appears and type in numeric code. Only some codes have been confirmed to work on WebTV for Dreamcast, others might not work on this release. The time window for entering in the code is also extremely small and not easy to predict, making testing the codes extremely difficult.
