v1 did not work with those models. Version 2 was widely criticized as it required the user to open the console and, therefore, voided the warranty. The company responded to this criticism by releasing Swap Magic v3, which did not require any opening of the console. CODER Swap Magic v3.8 (also known as CODER) was released, which adds the ability of loading Action Replay cheats into the booted game, as well as the ability to load an ELF file from usb or memory card. However, some users have complained that CODER has some compatibility issues as well as known bugs. For example, some games that work on v3.6 do not work with CODER. Consequently, v3.6 remains the most popular version of Swap Magic, though the ability to boot an ELF file allows for soft modding of the PS2. References PlayStation 2
