Arch Linux User Repository

Please use depends/source/sha256sums_arch for different architectures, e.g depends_x86_64/depends_i486. (I don't know if i386 is valid in PKGBUILD because ArchLinux32 only uses i486, i686 and pentium4.) And do not use unzip in prepare, just remove noextract and bsdtar works just fine. The unzip may cause an error because unzip is not in makedepends. Add a symlink at /usr/bin/gosumemory will make it more convenient. Also, according to the guideline, this package should be renamed to gosumemory-bin.

Remove osu as a dependency. I use osu!stable with my own wine prefix and setup and the osu aur package doesn't seem to successfully work.
