I have been having trouble loading games on my ps2 using HDLoader and realized its because of something called "mode 3" I have no idea what it is or how I can obtain it to make the games playable- I was wondering if someone could please fill me in. Thank-you

Also this might be a related question but I use HDLDumb to transfer files from my pc onto my hdd, and at the bottom there is a checklist, when would I use them/know to use them?
