Installing FreeMCBoot on a memory card has been made infinitely easier thanks to FreeDVDBoot! This doesn't require you to find a pre-loaded memory card, perform a swap trick, or have a modchip. This method is without a doubt the easiest method of installing FreeMCBoot on a completely unmodified PS2! As long as you have a USB drive on hand and the ability to burn a DVD, you're all set assuming you have a compatible console.
Keep in mind that FreeDVDBoot is completely reliant on the specific DVD Player version your PlayStation 2 has. With time FreeDVDBoot will be ported to work on more consoles, but for the time being you need to make sure your console is on a specific version. At the moment, every Slim console works with this method, with more support expected for Fat consoles.
