Hi, Can anyone help me on this one i dont know if it is right
I shrink my Gta iso from 1.16 gb to 835mb
i use the prx decepyt but i dont know how to use the UMD gen 2.00
can any one help me in the process
i have been trying to get the GTA for 6 hours still trying but can work...
zzzzzz
i dont understand this part
ou will need the iso of GTA to be able to continue, I will not give the means of obtaining it, therefore don't ask me on this subject.

Once the iso obtained, it will be necessary for you to extract all the files from the iso (use umdgen).

Then, place PRX2_0_0 folder (in PSP_GAME\USRDIR folder) has the root of your memory stick.

Execute then DecryptPRX, it will create in PRX2_0_0 folder somes files with dcr extensions, remove all the prx files and replace with the dcr files created (remove the .dcr extension) (to replace the crypted prx by the deciphered prx).

Then, recreate the iso with all the files which you had extracted AND PRX2_0_0 folder containing the deciphered prx.

Now you have iso on the good format

follow the thread that has all the tools already together.. it should still be near the top of the forum.

umd gen... file, open, select iso, highlight both folder and file on right side of app, right click, extract selected.
