Seeing the huge number of questions on how to install Battlefield: Bad Company on PS3 without the pre-order invite, we have got a simple way for you.
1. Download and install PS3 Proxy (http://www.ps3news.com/forums/downlo...o=file&id=3673).
2. Download [Register or Login to view links] to your PC.
3. Once installed enter your computer IP address in the IP adress box. To find your computer IP, go to START > RUN > CMD > IPCONFIG, and note the IP address, and enter it in PS3 Proxy.
4. Check "PS3 Mode"
5. Press "Start" (disable any firewalls if you have issues starting it at this point).
6. Go to your PS3 and start the download for Ratchet and Clank Demo.
7. PAUSE the Demo at 1%. Please note I am using the USA version of Ratchet and Clank (other regions please substitute accordingly).
8. Go to your Internet connection settings, select CUSTOM (not easy), and skip through all the options and enable the use of Proxy Server.
9. Enter the IP address that you entered for PS3 Proxy on the Internet connections menu on PS3 (besure ports are same).
10. Finish and test connection and you should connect to the PSN just fine.
11. Go to PS3 Proxy and check under the "logs" tab to see if anythign appeared, if you see text there then PS3 Proxy is working.
12. Now go to the "Replace files tab", and insert the PKG url for Ratchet and Clank on left box. USA users that PKG url is here:
13. Other PSN regions you can see the download URL in the Logs tab of PS3 Proxy, or HERE.
14. On the right box under Replace files, click drop down button and locate and double click on the Battlefield PKG file.
15. Go back to your PS3 now and resume the Ratchet and Clank Demo you paused earlier at 1%.
16. Battlefield should now be downloading to your PS3 (it will still show as Ratchet and Clank but will actually install BF).
