A legend?

[dust2dust]

yes its possible but it means stuffing a knife in ps2 tray to open it everytime u want to boot a game
very very risky so many ps2 r broken this way
the safest way is to buy a chip
depending were u from pal ntsc what chip is best for u
pal best option is messiah rough price guide with fitting is somewere in region of £100
sounds expensive but not really
no ar2 needed saves u £30
all games boot np just pop in let it work
