which Affiliates should I use to play ps game?

you need ePSXe from www.epsxe.com. I suggest you download 1.6, 1.7 and 1.5.2 and place them in separate folders (some games work better in one version than in the others; as a rule you need 1.5.2 for squaresoft games). 1.7 will also need 'zlib1.dll' in its folder (google will find it in no time). You will also need a BIOS file in each versions' bios folder, googling 'SCPH1001.bin' will get you the bios file. Plugins are also needed and can be downloaded from the sticky in the technical help section. Extract the archive to the 'plugins' folder in each version.
