vic-ii

A Commodore 64 emulator obsessed with getting the hardware right. One PAL C64 emulated in depth: cycle-accurate 6510 and VIC-II, physically characterised 6581R4AR SID, CIA, cartridges and REU, plus a cycle-driven Commodore 1541 with fastloaders and copy-protected disks. Native macOS, Windows and Linux. Written in Rust.

An open-source emulation framework designed as a virtual laboratory for exploring, building, and modifying classic computer systems in real-time.

Turn a real Commodore 64 into a programmable display + audio device via Ultimate 64 or TeensyROM+ — video, SID-music scopes, webcam, MIDI/ASID synth, WLED, generative visuals, overlays, playlists.

A device that allows switching of both the Kernal ROM image AND the video mode (PAL/NTSC, using the VIC-II² Switcher Card)

Handling Chinese text on the Commodore 64

**Write code with AI. Run it instantly on real Commodore 64 hardware. Let the agent inspect the result and iterate.**

Cycle-accurate Commodore 64 + 1541 emulator. Runs real games and demos.

Convert64 — layered, high-precision image converter that outputs legal Commodore 64 (VIC-II) graphics. Per-layer dithering, sub-pixel nudging, cell pins/locks, accurate C64 preview, exports for Koala/Art Studio/charsets/sprites and every assembler. Pure Rust: egui app + CLI + MCP server.

PAL C64 engineering reference for screen double buffering, fine scrolling, Color RAM beam racing, and VIC-II timing.

PAL C64 demoscene release in ACME 6510 assembly: precomputed XYZ wireframe cube, three-voice SID music, beat-reactive zoom/spin, safe raster IRQs, and live SPACE section transitions.

Convert SID tunes to MIDI by running them on a cycle-exact C64 emulated in pure Python: NMOS 6510, VICE CIA and VIC-II ports, reSIDfp SID. Passes 878 of the 881 VICE exit-code test programs it can run. No dependencies; C64 ROM images not included.

A Commodore 64 emulator for the Raspberry Pi Pico W and Pico 2 W, written in PureMetal: cycle-counted 6510 (Thumb-2 on the RP2350), VIC-II, SID and both CIAs on two cores, NTSC 60 fps by default, LAFVIN ST7796 panel, Bluetooth SID audio, .PRG/.D64 loading - plus a Windows version with debug panes. No ROMs included.

Audited PAL C64 text-mode intro: custom charset titles, animated VIC-II raster bars, fine scroller, SID arpeggio, reproducible builds, and GPLv3 tooling.

TinyToolBoxC64 is a web page to help you to to easily adjust all registers of your VIC II for your graphics projects.

Suite diagnostica video in Assembly 6502 per chip VIC-II (Commodore 64). Ottimizzata per la calibrazione di monitor CRT e moderni upscaler.

GPLv3 PAL C64 raster-polled megademo with a custom charset logo, fine scroller, animated sprites, plasma, color waves, raster bars, reproducible builds, and releases.

Reusable Python C64 and SID emulation-core components: CPU, memory, CIA, VIC-II, SID, playback, timing, and forensic primitives.
