A foobar2000 input decodes .sc68, .sndh, .snd format.

Based on https://sourceforge.net/p/sc68/code/HEAD/tree r600 version (2015-11-28)

(Since I think this is the best version for emul effect through my test)

Changes I made:

1. Move configuration from right-click menu to Preferences → Playback → Decoding → SC68 input and fixed the issue that the change in config can't be applied immediately.

2. Added seeking function. Now you can seeking sc68 songs!

3. Upagrade the project compatibility to MSVC 2022 C++ 17 standard and foobarSDK-2025-03-07. Use project references instead of static library to link.

4. Fixed address loading issues for some replayers

5. Merged SNDH Database of r713 to this version

6. Added a macOS version of the foobar2000 component (Apple Silicon / arm64).

   • sc68-fb2k-mac/Makefile compiles file68/libsc68/unice68 and the foobar2000 SDK sources directly instead of linking a prebuilt SDK build (bypassing autotools the same way sc68-msvc bypasses it with a hand-written config.h).
   • Run make package in sc68-fb2k-mac/ to produce a distributable foo_sc68.fb2k-component; see that Makefile's header comment for the one prerequisite (an unpacked copy of the foobar2000 SDK next to the sc68-fb2k-mac/ folder).
   • The Preferences -> Playback -> Decoding -> SC68 page is reimplemented for mac as a native NSViewController built entirely in code (no .xib), exposing the same settings as the Windows dialog: sampling rate, default track length, aSIDifier, YM engine/filter/volume model, L/R blend, and the Amiga low-pass filter. Unlike the Windows dialog there's no separate Apply/Reset step -- each control applies immediately, matching how foobar2000's own sample component behaves on mac.

7. Fixed the "Default length (s)" setting having no effect (a pre-existing bug in libsc68, fixed on both platforms).

Compatibility

• foobar2000 v2.0 or newer.
• Windows, 32-bit ONLY. Built against the foobar2000 SDK (2025-03-07).
• macOS, Apple Silicon / arm64 ONLY.

Building from source

Windows

Prerequisites

• Visual Studio 2022 with the Desktop development with C++ workload (and a Windows 10/11 SDK).
• The official foobar2000 SDK (2025-03-07 or compatible).
• WTL 10 (Windows Template Library).

Directory layout

The project files reference the SDK with system environment variable FB2KSDK. So, you just need to add the variable with SDK loacation to your system then the project will recognize it.

WTL MUST be placed as below:

├─ Foobar2000SDK-2025\
│  ├─ foobar2000\
│  │  ├─ SDK\
│  │  ├─ helpers\
│  │  ├─ shared\
│  │  └─ foobar2000_component_client\
│  ├─ libPPUI\
│  ├─ pfc\
│  └─ WTL10_01_Release\Include\        <- WTL goes here

Build steps

1. Open sc68-fb2k.sln.
2. Add all .vcxproj in foobar2000SDK (except foo_sample) and sc68-msvc\zlib\zlib.vcxporj to the solution. Then add all these as references to foo_sc68.
3. Build Release | Win32 and the post event will pack dll to .fb2k-component automatically

macOS

Built with a plain Makefile + clang, not Xcode -- no project file to open. Unpack the foobar2000 SDK next to sc68-fb2k-mac/ (i.e. ../SDK-2025-03-07, sibling of both sc68-fb2k-mac/ and sc68-fb2k/) from https://www.foobar2000.org/SDK, then from sc68-fb2k-mac/:

make            # build/foo_sc68.component
make package    # ^ plus build/foo_sc68.fb2k-component (the distributable zip)
make install    # ^ plus copies it into ~/Library/foobar2000-v2/user-components/foo_sc68/

See sc68-fb2k-mac/README.md for details.
