when did ps3 become backward compatible to play ps2 discs?
anyway, go to Kafico Trade Centre Opp. Tuskys Imara, Next to Paul Cookies Mans behind archives. the shop is called Vivid Gold shop G-15. Their numbers are +254 724 925236, +254 725 658773, +254 703 479072
I dont know how much they charge, depends on what needs to be replaced.
