What is SIDquake?

Ship Your Music

SIDquake makes it super easy for Commodore 64 musicians and artists to take their SID compositions and package them into ready-to-run executable PRG files. No assembly knowledge required. No complex toolchains. Just upload your SID, pick a visualizer, and export.

Analyze

Deep-dive into any SID file's internals. View load addresses, init routines, play calls, memory ranges, SID chip models, clock speeds, and CPU cycle usage — all parsed in real-time via WebAssembly.

Browse HVSC

Access the entire High Voltage SID Collection directly from your browser. Navigate thousands of SID tunes, preview them with in-browser playback powered by reSID, and select tracks for export.

Export PRG

Generate executable C64 PRG files bundled with beautiful visualizer effects. Choose from multiple visualizer styles, customize colors, add logos, and compress with TSCrunch — all in the browser.

The Legendary SID Chip

The MOS Technology 6581/8580 SID (Sound Interface Device) is the legendary sound chip at the heart of the Commodore 64. Designed by Bob Yannes in 1981, it was revolutionary for its time — a synthesizer-on-a-chip that gave the C64 its distinctive, unmistakable sound.

With three independent oscillators, each capable of sawtooth, triangle, pulse, and noise waveforms, plus a multi-mode resonant filter and ring modulation, the SID was years ahead of its competition. It turned a home computer into a genuine musical instrument.

The original 6581 (found in earlier C64 models) and the revised 8580 (in the C64C) each have their own character. The 6581 is known for its raw, gritty filter and louder volume, while the 8580 offers cleaner output and better-defined waveforms. Both are beloved by musicians and collectors worldwide.

The Demoscene & C64 Culture

“The demoscene is digital art as a competitive sport.”

The demoscene is a vibrant international computer art subculture that emerged in the 1980s. Groups of programmers, musicians, and graphic artists collaborate to create demos — non-interactive audiovisual presentations that push hardware to its absolute limits.

In 2020, the demoscene was officially inscribed on UNESCO's Representative List of Intangible Cultural Heritage in Finland, Germany, and Poland — a recognition of its unique artistic and cultural significance.

The Commodore 64 remains one of the most active demoscene platforms decades after its release. New demos, music disks, and intros are still being created today, with musicians composing fresh SID tunes and coders finding new tricks on the venerable 6510 CPU.

Major C64 demoscene events include X Party, Revision, Transmission64, and BIT Party among many others, where sceners gather to compete, collaborate, and celebrate this unique art form.

SID Music & HVSC

SID music is a thriving art form with an incredible heritage. Legendary composers like Rob Hubbard, Martin Galway, Jeroen Tel, Ben Daglish, Chris Hülsbeck, and Tim Follin defined the golden age of C64 game music. Today, the demoscene keeps the SID alive with an amazing community of musicians still pushing the chip to new creative heights.

The High Voltage SID Collection (HVSC) is the definitive archive of C64 SID music, containing over 57,000 tunes by thousands of composers. Maintained by a dedicated team of volunteers, HVSC preserves the complete history of SID music from 1982 to the present day. SIDquake provides direct browsing access to the entire HVSC collection.

Under the Hood

WebAssembly Emulation

SIDquake runs a full MOS 6510 CPU emulator compiled to WebAssembly. This allows real-time analysis of SID files directly in your browser — no plugins, no downloads, no server-side processing.

reSID Playback

In-browser SID playback is powered by reSID, the industry-standard cycle-accurate SID chip emulator. Hear your tunes exactly as they'd sound on real hardware.

TSCrunch Compression

Exported PRG files can be compressed using TSCrunch, an efficient C64 packer. This creates self-extracting executables that fit more into the C64's 64KB of RAM.

KickAssembler Players

Visualizer routines are written in 6502/6510 assembly and compiled with KickAssembler. Multiple load addresses ensure compatibility with any SID file's memory layout.

Genesis Project

SIDquake is part of the Genesis Project family of C64 tools and resources. Genesis Project is an active demoscene group dedicated to preserving and advancing Commodore 64 culture through modern tools and new productions.
