The process involves replacing an existing version of a custom firmware installed on a PlayStation 2 memory card, enabling the console to boot homebrew software without requiring a modchip. This allows users to access enhanced functionalities and utilize custom applications.
Maintaining an up-to-date version ensures compatibility with the latest homebrew releases, security improvements, and potential bug fixes that enhance the overall user experience. Earlier versions might lack essential features or exhibit compatibility issues with newly developed or updated homebrew programs.
