ESR Disc Patcher



tools

ESR is an application that lets you play certain PS2 backups without modifying the system as long as these backups are specially patched. ESR is always used in conjunction with FMCB: FMCB loads ELF files like ESR and ESR loads backup games.

The way ESR plays backups is by taking advantage of two of the main selling points of the PS2: its DVD drive and its ability to play Video DVD.

The standard format used for DVDs on the PS2 is UDF (Universal Disk Format), which greatly supports multi-session discs.

What ESR does is patch the ISO image of the game to include two different data sessions or tracks, the first one, and the one that is immediately accessible to the CDVD drive is a dummy track that resembles that of a Video DVD, fooling the CDVD drive into thinking that a Video DVD has been inserted. Since playing recorded Video DVDs is allowed on the PS2 as the machine does no other check on the media, the CDVD drive gives green light to the disc as a supported disc.

With the CDVD drive fooled it is now time to mount the DVD using the second session, which contains the game itself, since we have already fooled the system into booting ESR and we have already fooled it into recognizing our disc, we can now freely load ELF files from there, so all ESR has to do now is read the SYSTEM.CNF file to obtain the path of the game’s main ELF and load it, effectively running our game.

ESR no longer works on the PS3 (Sony is not that stupid this time around), but it still work on every PS2 model, with the difference that SCPH-9000X models have patched FMCB, so Swap Magic or a modchip are better options there, and if you have any of those then there’s no real need for ESR.
