4-in-1 BIOS, S-Video & Composite A/V Kit

A kit combining the two modifications most ColecoVisions want: a switchable BIOS and better video out.

The BIOS half

• A stock console holds every retail game on its title screen for twelve unskippable seconds.
• A four-in-one BIOS carries several versions - typically the original, a no-delay one, and variants for compatibility - selectable rather than fixed, since the earliest no-delay hacks broke some software.

The video half

• The console leaves the factory with RF only. The kit adds composite and S-video, the latter keeping brightness and colour on separate wires so nothing has to be untangled at the display.
