Use an emulator like PCSX2 (PC) or AetherSX2 (Android) .

Use ImgBurn on Windows or the dd command on Linux to create clean ISO images from your physical collection.

Most PS2 archives come as large files. For the best experience, you may need to convert or split them depending on your storage method.

If you are using a USB drive formatted to FAT32 for an original PS2, files larger than 4GB won't fit. You must use tools like USBUtil to split the ISO into smaller chunks that OPL can read.
