well I am fairly new to this but from the item description it says it requires game shark or action replay to work so that is an indication that yes almost 100 % sure you have to use the swap method. to my knowledge ALL no solder or usb mods use swap method. but if u want easy try the new no solder mods at this url. I am getting one next pay period it is plug and play and supports DVDr and CDr wich is unheard of for a no solder. anyway here it is..... also they sell pre messia chipped PS2s hehe
