Zakuro v0.2.20

On Windows, unzip zakuro-windows-x86_64.zip and run zakuro.exe. On Linux, extract zakuro-linux-x86_64.tar.gz and run ./zakuro, which needs the ALSA library (libasound2 on Debian and Ubuntu, alsa-lib on Arch).

Games need to be decrypted ROMs. Recompiling a game, which makes it run much faster, needs a C compiler. Zakuro uses gcc or clang when the computer has one, and otherwise offers to download Zig, which needs no installing, into its own folder.
