Hello everyone! I'm currently making iso files out of my old ps2 games. I'm thinking of trying to fit as much of them in one dvd. Some time ago, I came upon this compression tool that really did well (it's not a rar, zip, or 7z) but I just forgot what it was.
Anyway, can you please recommend the best compressor for PS2 iso files? I really want to keep all my ps2 games in a box and send them into the attic and have only a few dvds around that contains compressed iso files.
Thanks again in advance:)
