Since version 2.0.7 Beta Patch#2, NervOS has a new feature in the installer which allows you to patch ONLY the files you want.
This is useful for future versions if there is a bug fix version, you just need to follow this readme.

Available files to patch:
* 3xxkernel.prx
* ctrl.prx
* loadexec.prx
* modulemgr.prx
* nosautoboot.prx
* patchexit_driver.prx
* system.prx
* umdexec.prx
* usb.prx
* usbhostfs.prx
* bridge.pbp

Other files must be copy/pasted manually. 

in this folder create a file called patch.txt.
Add the files you want to patch(copy and replace old ones) into this folder.

in patch.txt add the name of the file to be patched. (the old one is only replaced if the name of the file matches the any of the files in the list).

example, you want to patch the installed system.prx, just place the new system.prx in this folder and add this to patch.txt:
system.prx

it's easy :)

Run the installer and choose Patch Files, Press X to continue AGREEING I TAKE NO RESPONSABILITY for any problems caused by NervOS.

I hope this information is useful :)
