ESR

ESR
ESR is an homebrew application developed by ffgriever for the Sony PlayStation 2 console. ESR allows you to run DVD discs patched to DVDV format on unmodified PlayStation 2 consoles. In other words, it allows the user to play game backups burnt onto blank media.

Discs must be manually patched to be booted with ESR, and they must be DVD media. CD media is not compatible with ESR; anyone wishing to boot a CD-based game will have to convert it to DVD media. Information on doing so can be found here.

There are multiple versions of ESR, but the simplest and most recommended is the current GUI test. This is a release of ESR with a GUI and a few useful settings. A couple games are known to work only using this with some of those options, but it's still a test. You can find the GUI test here.
