Yes, the PS2’s USB ports are limited to approximately 1.5 MB/s (compared to a DVD drive’s 3–5 MB/s). However, USBUtil v2.1 optimizes how data is read. Games that stream data constantly (like Final Fantasy X or Kingdom Hearts ) run flawlessly. Only games with heavy FMV (Full Motion Video) streaming—like Metal Gear Solid 2 —might exhibit slight choppiness.

Since FAT32 drives cannot hold a single file larger than 4GB, USBUtil splits these games into smaller ".ul" files that OPL can read.

Have a specific game that won't boot? Leave a comment (or check the PS2-Home forums) for compatibility lists. Happy gaming.

Alternative: For better speed, use a Raspberry Pi or an internal HDD via a network adapter. But for a , this is king.
