Now that you have your PSXPS1 and put it in your disk drive and wait for it to load. I use Silent Hill 1 for PS1 as my trigger disk, I also know that THPS 3, Cool boraders1 and 2 work. That is used to launch.ELF files on a PS2.įinding a PSXPS Game that works as a trigger disk can sometimes be hard, I once seen a list online but can not seem to find it anymore, once I find it I will be sure to add it. When you load a PSXPS1 game in a fat PS2, the ps2 looks for the file on your memory card called BOOT.ELF Having that file modified the ps2 will boot uLaunchELF, a PS2 homebrew app. Now that you have the files your going to need, it is time to find a PSxPS1 trigger disk.
