GUYS! I DID IT! I HAVE FOUND THE WAY TO RUN PAID APPS!
MY NFS SHIFT WORKS NOW!
As all we know, applications are being installed on SD unpacked from APPS. Registry of BADA OS is encrypted and is situated in the hidden phone memory and can be only accessed with the sTune. So i decided not to touch the registry but to try to replace the content of the trashy APP with the content of a good game (such as NFS Shift or any paid app) and I have also replaced IDs in XMLs. And it Worked!
I installed ARDefender, renamed exe s3e.exe to ARDefender.exe, the Data folder was deleted and repleced with the folder of NFS and i also did some changings in IDs of XMLs in "Info" folder and Singnature.xml.
Now when i start ARDefender, my Wave loads NFS shift.
IT WORKS!
I think any game will run that way. All we need is unpacked content! Who has any - upload it!
