I have a Ps2 with SwapMagic, but i know the Swap don't work with DVD9, soo... i play with my "GT4 Original" if i want play with.
But, one day i try to play with... and my Original Game don't work anymore... The DVD just try to turn without success... the DVD is Jam and the game don't start.
I suppose all DVD9 Original Game don't work but... Why? Because all other original DVD5 game work normally.
Im not sure about the version because i dont have my Ps2 with me actualy, but... this is a SlimVersion V13 or V14... I bought it New: "Mars 2006"
Im not sure the laser is the problem, because all backup game or original game on DVD5 work well, but im not a pro...
(I try to clean the laser last week, but no change after that)
My friend try my GT4Original with is own SlimPs2 and the game work well... my original GT4 is clean like the first time.
(Do you have many advice for me about cleaning my laser, because last week, i don't take risk... probably my cleaning don't be enought, but im not sure too)
Its a slim so you can see the laser, just take a q-tip and small amount of isopropyl alcohol, gently rub the laser lens, and then use the dry end to remove excess alcohol.
You can also use a can of compressed air to clean underneath the laser, and under the cover to see if that helps.
