1) The easiest way is to use this multi-formats patcher: http://projects.sappharad.com/tools/multipatch.html

- Location of patch file => Select the patch (PSGEN2-US_Beta_Version.xdelta3)
- Location of file to patch => Select the japanese iso
- Save patched file as => Select a path and a name for the english iso

2) Then click on "Apply Patch" to apply the translation patch to the iso.

3) You'll get an english patched iso ("PSGEN2-US_Beta_Version.iso"), that you can either use with a PS2 emulator or either burn it on a disc to use it on your PS2 system (if your PS2 can read burned games). If you choose to burn it, remember this is a CD game so you need to burn it on a CD, not on a DVD.
