It must've been over 5 years ago when I decided to buy the HDD adapter for my phat PS2 and a 500gb IDE HDD but I used Free MCboot to get HDLoader running and 99% of the games I wanted to play actually ran without any problems. Of course that was 5 years ago and so far, I see OPL as the latest program to use for loading PS2 ISOs from HDD but at the time, the compatibility was still in its infancy. Any idea if OPL is almost 100% or should I stick with HDloader?
