ps2 dvd backup

[droppie]

i use the ar2 disk first till the mainscreen
then i put in an original playstation dvd, i wait for 30 sec.
then i start the game without codes. i press x, and then when the screen goes black i push eject till its yellow and opens,

now i do the swap

but it only work with the same games (gta origanal- gtabackup)
