Arch Linux

Description:
The core updater does not work out of the box because the user does not have modify permissions for /lib/libretro.
Since the updater does not work, it should be disabled by default.

retroarch.cfg contains the line
`menu_show_core_updater = true`

By simply changing this to false, the core updater is hidden from the main menu, thus preventing the confusion of it inevitably not working.
The entire online updater can be disabled using `menu_show_online_updater = false`, but I think just disabling the core updater is best, since Arch doesn't package the shaders, cheats, thumbnails, etc. and those must be downloaded from the updater.

Attached is a patch that doesn't work, and I'm not sure why. It looks identical to your existing patch, but with the added change above. But installing the package produced by makepkg with this patch and your PKGBUILD just results in getting the default unedited retroarch.cfg. Not sure what I'm doing wrong, but it shouldn't be difficult for someone who knows what they're doing to patch it :)
