PlayStation 2
Open PS2 Loader (OPL)
OPL is typically used to load game backups on the PS2. See the PS2-HOME Forums for resources on installing & running OPL.
Warning
OPL is sensitive to files being fragmented on USB drives and SD cards (MX4SIO/SIO2SD). This means that you should only write one ISO at a time!
Igir has a --writer-threads <threads>
option to limit the number of files being written at once. You can use the option like this:
Replace the E:\
drive letter with wherever your USB drive is:
Replace the /Volumes/PS2
drive name with whatever your USB drive is named:
