FreeMCBoot allows homebrew programs to be launched without a trigger disc required unlike PS2 Independence. | FreeMCBoot allows homebrew programs to be launched without a trigger disc required unlike PS2 Independence. | ||
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 work on the very newest PS2s (SCPH-9000x model with BIOS 2.30 and up) but will work on all models prior to that. | It does not work on the very newest PS2s (SCPH-9000x model with BIOS 2.30 and up) but will work on all models prior to that. | ||

Allows to run burnt CD/DVD | Allows to run burnt PS2 CD/DVD on a PS2 without modchip. It is needed to have FreeMCBoot/FreeHDBoot, Fortuna or SwapMagic in order to launch ESR. | ||
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. | |||

It is possible to exploit | It is possible to exploit Network-capable games, to inject codes!!! | ||
This is perfect for Slim PS2 and people which can not move files to the MC! | |||
TnA scarcely mentioned that method since January 2019, like it can be seen in the comments of @Haldrie's video about the time-swap! TnA got the basic idea from some discoveries someone else mentioned. | |||
The problem is to either inject it elsewhere, or find a way to run it! | |||
The existing FreePSXBoot exploit chain | ==PS1 Savedata exploits== | ||
The existing FreePSXBoot exploit chain does not work on the PS2 (mainly inside mcman), due to the fact that the internal structure is different. | |||
