Playstation Underground Demo Discs: Jampack Winter '99 Codebreaker Codes (NTSC-U)

This page contains CodeBreaker cheat codes for Playstation Underground Demo Discs: Jampack Winter '99 (NTSC-U) for the Playstation 1. Depending on if you're playing this game on a physical console or an emulator will determine how you use the codes found on this page. People using a physical console will need to purchase a physical CodeBreaker device to use the codes.

Anyone who is using an Emulator will have a much easier time getting these codes to work (assuming your Emulator supports them). One of the most popular Emulators for the Ps1 is ePSXe and if you'd like to learn how to use the codes on this page for that Emulator, check out my how to get cheat codes to work with ePSXe guide. If you don't see the code you want on this page I recommend you return to my Playstation Underground Demo Discs Index and choose a different section.
