MH Online: source code of the emulator and the launcher's music decoder

The emulator is PPSSPP v1.20.4 (https://github.com/hrydgard/ppsspp, commit fa50bb1976065c4f8b1b47af227d367fe9771555) with the changes
described in MH-ONLINE.md. It's licensed under the GNU GPL, version 2 or later: see LICENSE.TXT.
music-decoder/ is the launcher's ATRAC decoder, built on the emulator's ext/at3_standalone.

To build it on Windows, see MH-ONLINE.md. It uses Visual Studio with the C++ tools.

Left out to keep this archive smaller, because the Windows build doesn't use them, and available from
the upstream repository at that commit: pspautotests, ios/MoltenVK, SDL/macOS, and ffmpeg's folders for
other systems (Windows10, linux, android, ios, macosx, wiiu, blackberry, symbian, tvos, tests).

This archive contains no game files.
