These files can be completely ignored, as they will be updated with any edits made to the source files should any [[#updating_your_package|new version of the package]] be made.

 </code> </code>
 +
 +==== Updating your package ====
 +
 +If you kept the original package files, it is simple: make your adjustments and increment the version number however you see fit.
 +
 +<file - .PKGINFO>
 +pkgname = nes-alter-ego
 +pkgver = 1.0.1-1
 +pkgdesc = Alter Ego - A freeware puzzle game by Shiru, Kulor, Denis Grachev.
 +arch = any
 +group = sys-nes
 +packager = your_name
 +url = https://wiki.batocera.org/start
 +
 +</file>
 +
 +<WRAP center round info>
 +The ''.PKGINFO'' will now contain the ''size'' and ''builddate'' tags. These are updated automatically upon compilation, so don't worry about them.
 +</WRAP>
 +
 +You may notice that in your ''userdata/'' folder for the package, there are additional folders and files that you had not placed there yourself. These have been automatically generated by ''batocera-makepkg'' (such as if you had used ''.BATOEXEC'' it will create the ''userdata/system/pacman/batoexec/nes-alter-ego_0'' file which is a copy of the ''.BATOEXEC'') and can be safely ignored; they will be updated along with the rest of your package.
 +
 +When ready, follow the instructions from the [[#create_the_package|Create the package section above]]. If you receive an error that the package already exists, that means you forgot to increase the package version number or that you have already compiled it.
 +
 +<WRAP center round important>
 +When updating packages, you **must** increment the version number, even for minor changes. Otherwise, it may cause corruption if the user has the same numbered package installed upon attempting to update to a newer version.
 +</WRAP>
 +
 +==== Remove your package ====
 +
 +When you're done testing or just want a clean slate to work with. Do note however, a ZST file is not actually required to remove a package. Simply enter the name (''pkgname'') of the installed package in the following command:
 +
 +<code>
 +pacman -R <pkgname>
 +</code>
 +
 +This is version independent.
 +
 +For example:
 +
 +<code>
 +pacman -R nes-alter-ego
 +</code>
 +
 +which would result in:
 +
 +<code>
 +checking dependencies...
 +
 +Packages (1) nes-alter-ego-1.0.0-1
 +
 +Total Removed Size:  1.33 MiB
 +
 +:: Do you want to remove these packages? [Y/n]
 +</code>
 +
 +Press ''[Y]'' followed by ''[Enter]'' to complete the removal.
 +
 +<WRAP center round tip>
 +To see a list of installed packages and their version numbers, run ''%%pacman -Q%%''.
 +</WRAP>
 +
 +===== Hosting your own repository =====
 +
 +It is possible to [[:pacman_package_manager|host your own repository]] to test downloading and installing packages via ''batocera-store''.
