PS2 Region Codes on PS3

I assume you bought a PS2 game that works on your PS2 system but not on your PS3 system since a PS3 game will never work on a PS2.

Since not all PS3 systems can play PS2 games, you need to first check the model number of your PS3 system. If you look at the back of your PS3, there should be a serial number somewhere that starts with "CECH", followed by one more letter and a couple numbers (e.g. "CECHC02"). Unless the model number starts with "CECHA", "CECHB", "CECHC", or "CECHE", you won't be able to play PS2 games on your PS3.

If your PS3 can play PS2 games, then you need to make sure that the region of the PS2 game matches the region of your PS3. The region of the PS2 game can be found in the upper-right corner of the front of the box the game came in. The four regions are: "NTSC U/C", "NTSC J", "NTSC C", and "PAL".

Once you know the model number of the PS3 and the region of the PS2 game, you can tell if the PS2 game should work on the PS3. Use the following chart to determine if your game and system are compatible:

Last two digits of your PS3 model number: Playable PS2 game region
00: NTSC J
01: NTSC U/C
02: PAL
03: PAL
04: PAL
05: NTSC J
06: NTSC J
07: NTSC J
08: PAL
09: NTSC C
11: NTSC U/C
12: NTSC J

it sounds like a version conflict to me ie a NTSC copy of the game with a pal PS3 or visa versa.
an excerpt from wikipedia
"Two of the seventh generation of video game consoles have regional lockout, so games imported from other countries cannot be played on foreign versions of those consoles without some form of alteration to bypass the lockout. However, a number of games for the Xbox 360 have been confirmed as region free and will play on a unit from any region, although it is up to the publisher if a game is region free or not. Like the CD-i and the Panasonic 3DO, the PlayStation 3 is one of the few home consoles to be advertised as region-free.[2][3] However, while region free for PS3 games, there is region locking for backwards compatible PS2 and PS1 games, as well as DVD and Blu-ray Disc movies. Additionally, some games separate online players per region, such as Metal Gear Solid 4 Online. A PSN store only contains content for its own country, for example the UK store will not supply usable map packs for an imported US copy of Call of Duty 4. The PS3 actually supports hardware region locking for PS3 games as well, based on Blu-ray regions,[4] but as of current it is unused and all current region lockouts and separations are about online services."

Perhaps checking the video setting and game settings under "settings" in the home menu might help.

on the first ps3s but not now......im not sure bout the slim......mine plays ps1 2 3

If you live in Australia, you can only play UK or PAL Blu-Rays or those that are region free. DVD Region X doesn't work on the PS3.

Like the PSP, the PlayStation 3 is region free for gaming. All games available for the PlayStation 3 are region free, however backward compatibility modes (ie. PlayStation 1 and 2 games) are region locked. Blu-ray Disc and DVD region codes are also enforced.

Australia Comes in Region B and USA comes in Region A .

There is NO solution at present to run a different region Movie on a different region PS3

Games are Regional Free so it will play in any regional consoles

well for a start are you sure its 60gb cos only the 60gb plays ps1 and 2 games but the dvds thats a bit odd

Well, whatever location you set your playstation should set the region when you created your account. I don't believe they are hardlocked to regions. You could try adjusting the settings in the xmb, there are options for region control.

Hope this helps.

how to play dvd+ and - on the PS3 snd how to make it play PS2 games

The pal ps2 games and dvds will not play on a Japanese ps3 due to region coding. You can play all ps3 games and blu ray films because they do not use region coding. Some games will also play differently on a ps3, for example, Uncharted: Drakes Fortune (I highly recommend the game) will not have any blood on a Japanese ps3. The region coding feature can not be changed/modified. I would recommend returning Japanese ps3 and purchasing a European model instead if that is possible. Bon chance.
