HD Loader

HD Loader is a popular PS2 application with which PS2 users can play games using a PATA HDD. When Sony stopped making PS2 machines without Hard Disk it disappointed PS2 lovers. So PS2 independent developers came in contact and developed an open source PS2 software with which PS2 games can be played without original PS2 HDD. However it does not support all PS2 games.

Now HDLoader comes with its super powerful version 3.8C which supports many advanced features such as support for 1000GB HDD (previous versions support upto 137GB), faster reading speed from CD/DVD. It supports almost 95% PS2 games.
