Highly compressed PS2 ISOs are optical disc images that have been processed to significantly reduce their storage footprint, often by removing "padding" data or using efficient compression algorithms compatible with modern emulators. While a standard PS2 DVD ISO can take up nearly 4.7GB, compression can often reduce this size by 30% to 60%, and in some cases, even more if the original disc contained large amounts of empty data.
