This is just some info and a video tutorial I put together on how to make custom Day 1 saves for the Playstation 2 Codebreaker.
First of all we have the upgrade files to enable a Codebreaker to use custom Day 1 files. This has been tested by me on CB Version 8.0 and 9.2/9.3. This will not work on Version 10.x Codebreakers. To use the upgrade, all you have to do is extract the archive and paste the upgrade.bin file on the root of the pendrive you use for flashing Day 1 saves. The other file can install the upgrade directly to your memory card. I haven’t used it myself. I just leave upgrade.bin on my flash drive.
Download Pendrive.7z from the link above
The next tool is Omniconvert. This utility can convert codes between various cheat devices. For example, if there is no code that does what you want for Codebreaker, but the code you want exists for Action Replay, you can load that code into Omniconvert and convert it to a Codebreaker code that will work on your device. More detailed info can be found on the developer’s website. The attached download is for version 1.1.0 Beta, the latest version at this time.
