SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill explains how to decode and apply Sonic 3K Pattern Load Cue data so runtime art, boss assets, and act-transition graphics load correctly without tile corruption or frame hitches.

Core Features & Use Cases

  • PLC Table Decoding: Reads the PLC offset table and per-entry blocks to recover ROM art addresses and VRAM destinations.
  • Runtime Art Loading: Supports zone events, act transitions, and pre-decompression flows that refresh modified renderers after art changes.
  • Boss and Object Art Handling: Uses standalone decompression when art must be isolated from the shared level pattern buffer.
  • Use Case: A contributor can trace an AIZ transition, identify the correct PLC ID, and apply the matching loading path for seamless texture updates.

Quick Start

Use the s3k-plc-system skill to explain which PLC ID, loading routine, and renderer refresh path should be used for a specific Sonic 3K zone, transition, or boss art change.

FAQPage Schema
What is a Pattern Load Cue in Sonic 3K and how does runtime art loading work?▼

A Pattern Load Cue (PLC) is a data system that dictates how Sonic 3K loads art assets into VRAM during runtime. It works by decoding PLC offset tables and entry blocks to recover ROM art addresses, ensuring graphics load without tile corruption or frame hitches.

How do I decode PLC offset tables and entry blocks for Sonic 3K ROM parsing?▼

To decode PLC offset tables for Sonic 3K ROM parsing, read the per-entry blocks to extract specific ROM art addresses and VRAM destinations. This process recovers the exact loading routines required to refresh modified renderers after art changes.

How does standalone decompression handle boss and object art in Sonic 3K?▼

Standalone decompression handles boss and object art by isolating these assets from the shared level pattern buffer. This ensures that specific object graphics load correctly during runtime without overwriting or corrupting existing level tile data.

Why do I get tile corruption or frame hitches during Sonic 3K act transitions?▼

Tile corruption and frame hitches during Sonic 3K act transitions occur when the wrong PLC ID or loading routine is applied. Tracing the transition to identify the correct PLC ID ensures seamless texture updates and proper tile-range overlap tracking.

Can I use PLC table decoding for GPU texture refresh workflows in Sonic 3K?▼

Yes, PLC table decoding applies to GPU texture refresh workflows by organizing the Sonic 3K Pattern Load Cue system to support runtime art loading. It ensures that pre-decompression flows correctly update modified renderers after art changes.
