u could try this away it works useing no solder chips u first load ur gs2 then when it loads and u dont hear the cd spin u hold ur button till tray comes open then u take out the gs2 disk and put a real game in like gta3 or devil may cry something with a big TOC now tray will go closed by its self then u wait about 30 secs then goto the cheat code list change a code any one of them just change it or make a new code then hit start game with codes u dont have to trun any on then it will say updateing code list plz wait then u hold the button down again tray will come by its self u hurry and take origianl game out then put the copy in tray will then shut and the game will load on its own
the reason why it dose not say that in the diractions is casue a person came out with that boot not a company
u could always try swap magic disk i belive they would work with ace key there easier to use then gs2 u could always ask this guy he sells them cheap and would prob know if it would work
