I used SNOWLEO_MAC_Snow_Leopard_OSX86_64_For_INTEL_AMD_32 _64_MBR_GUID, search for it in google..
During installation make sure u check following options in customisation:
- kernel: chocolate kernel
- amd patch
- fakeSMC
- platform UUID
- drivers for your LAN/WAN
- legacy apple piicata
- Azaila audio
- drivers for your graphicscard
- and chameleon RC5 or one of the older
