This is invalid C++, and newer versions of MSVC reject it.
The database is opened via a relative path, so opening a file picker before opening the database can cause the database not to be found.
This is needed because SOUPER cartridges can trap MARIA's reads and handle them specially.
BupBoop uses this header, and older versions of MSVC don't supply it, so we supply it ourselves.
This is located at: http://tailchao.com/Audio/index.php#BupBoop It uses the zlib license, which is GPL compatible. This library is needed to emulate the sound hardware that "Rikki & Vikki" uses. It's an entirely separate chip included in the cartridge that produces 16-bit stereo audio. Note that BupBoop supplies a library called WinTone that provides DirectSound bindings, but we don't use it both because we already use DirectSound and because using WinTone would complicate `libretro` portability.
According to the author of BupBoop (and of "Rikki & Vikki"), this is necessary in order to play the music of that game properly.
This doesn't affect the sound of any other cartridge, but it's needed to play BupBoop audio (from "Rikki & Vikki") at full fidelity.
Note that this commit itself doesn't actually allow the BupChip to be used for anything, because the only way to supply music for the BupChip to play is through the CDF format.
This format allows song files to be supplied to the emulated BupChip for playback. It matches the format used by BupSystem: http://tailchao.com/BupSystem/index.php "Rikki & Vikki" is supplied as a CDF file, along with an unheadered `.bin` image and several music files.

Hi,
Here's a pull request with complete support for "Rikki & Vikki", including music. It adds support for BupSystem's BIN/CDF format, so that you can open the Steam
FoxBox.cdfin ProSystem and it should run fine.One of the commits contains a vendored copy of part of BupBoop, which is an emulation of the chip that this game uses. (The emulator, chip, and game were all written by the same author.) This library is under the zlib license, which is GPL compatible.
The first few commits were needed to build on MSVC 2019. If you'd like I can split those into a separate pull request.
There is a corresponding libretro pull request that contains this same code, ported over to the style of that fork.
