Opening excerpt (first ~120 words) tap to expand
c64-kb — Commodore 64 knowledge base for AI-assisted demo and game development A shared reference KB served via MCP. Combines Qdrant vector search with FalkorDB knowledge graph over C64 hardware, techniques, toolchains, and pitfalls. Designed to power AI agent loops that design and build C64 demos and games. The pitch LLMs trained on public C64 code suffer two compounding problems: their training data skews heavily toward cc65 patterns (which are common on GitHub but not idiomatic for demo-quality work), and timing claims are routinely wrong — raster splits at incorrect scanlines, sprite-multiplex cycle counts that do not fit in the badline window, SID filter cutoffs that differ between chip revisions.
