"System Data" does not alow a PS3 that can't normally play PS2 games the ability to play them. It only allows systems that can already play PS2 games the ability to play games that use a hard drive like Final Fantasy 11...
What if i have a 120GB ps3 can that work i download the PS3 sytem data and try games like Burnout 3 and Granturismo 4 does a 120 GB work please reply?
Only the 20GB, 60GB, and 80GB (all systems that have 4 USB Ports) can play PS2 games. If your system has only 2 USB ports, it does not have the necessary hardware to play PS2 games.
Here are the models that play PS2 games through hardware emulation:
CECHAxx (1st Gen 60GB)
CECHBxx (1st Gen 20GB)
Here are the models that play PS2 games through software emulation:
CECHCxx (2nd Gen 60GB)
CECHExx (2nd Gen 80GB)
Here are the models with no PS2 compatibility:
CECHGxx (3rd Gen 40GB)
CECHHxx (3rd Gen 40GB)
CECHJxx (3rd Gen 40GB)
CECHKxx (3rd Gen 80GB)
CECHLxx (3rd Gen 80GB)
CECHMxx (3rd Gen 80GB)
CECHPxx (3rd Gen 160GB)
CECHQxx (3rd Gen 160GB)
CECH-20xxA (1st Gen Slim 120GB)
CECH-21xxA (1st Gen Slim 120GB)
CECH-20xxB (1st Gen Slim 250GB)
CECH-21xxB (1st Gen Slim 250GB)
CECH-25xxA (2nd Gen Slim 160GB)
CECH-25xxB (2nd Gen Slim 320GB)
CECH-30xxB (2nd Gen Slim 320GB)
In order to find the model number look around the box or the console itself. The "xx" codes are replaced by the region. Here are the list of all used region codes in PS3 model numbers:
00 = Japan
01 = North America
02 = Australia / New Zealand
03 = United Kingdom / Ireland
04 = Europe / Middle East / Africa
05 = Korea
06 = South-East Asia
07 = Taiwan
08 = Russia / India
11 = Latin America
12 = Hong Kong
(09 and 10 aren't used)
Hope this helps.
There's an easier way to tell visually, the number of USB ports. If the PS3 has 4 front USB ports they're backward compatible. The current models only have 2 & aren't.
