This also allows | This also allows use of homebrew on unmodded systems without a functional disc drive. However, installation of the exploit to each individual memory card requires either an already exploited/modded system in order to launch the installer, or boot image that can load an app that loads ELF files (network adapter and hard drive also required). Copying from one memory card to another will not work. | ||

It does not yield code-execution, but once you have the ability to load code, you can access content on burned (Video-)DVDs, which have DVD-Video-content. This vulnerability is used in different apps like ESR or SMS and in varying 'formats' like ESR-Discs or simple Video-DVDs with extra-content. | |||
