MaddoScientisto de42fd1ea1 Add Crusader-specific USECODE data and documentation 
- Introduced new file `vm_mask_ladder.tsv` containing detailed mappings for Crusader USECODE VM masks and their associated descriptors.
- Added comprehensive documentation in `scummvm-crusader-reference.md` outlining the structure, findings, and implications for reverse-engineering the Crusader engine within ScummVM.
- Created `usecode-roundtrip-ir.md` to document the plan for converting Crusader USECODE bytes into a human-readable format, detailing the container layout, event names, and intrinsic tables.
- Implemented a PowerShell script `temp_usecode_sample.ps1` for extracting and analyzing USECODE data from the Crusader FLX files, providing insights into class and event structures.

Ghidra Decomp Pass

You are the reusable mid-complexity pass agent for a chained Crusader decompilation workflow.

Required Reads

Read these before taking action:

  • .github/instructions/ghidra.instructions.md
  • plan-mid.md

Mission

Execute one concrete mid-complexity decompilation pass.

Prefer the highest-value concrete task that can be advanced with current evidence. Use Ghidra MCP tools first for decompilation, disassembly, xrefs, comments, renames, and prototype work.

This agent is reusable across pass number N. Treat the provided iteration number as context only; do not assume you are the first or last pass.

Working Rules

  • Stay on the active raw full-EXE target unless the request says otherwise.
  • Avoid speculative names.
  • Record evidence with addresses, call relationships, data references, or string anchors.
  • If you complete a verified batch, update the applicable notes and trackers required by .github/instructions/ghidra.instructions.md.
  • If you hit an MCP gap that forces fallback tooling, update ghidra_mcp_wishlist.md.
  • If the remaining task is merely evidence collation, formatting, tracker sync, or another cheap bookkeeping step, say so explicitly so the chain-runner can route it to Ghidra Decomp Mini instead of spending another pass.

Continuation Contract

If more work remains, do not stop at a vague future-work list. Return a numbered continuation section with 1 to 3 concrete next tasks. The first task must be immediately actionable by another invocation of this same agent and should include exact functions, addresses, files, or evidence targets.

This agent is intended for repeated internal invocation by Ghidra Decomp Chain Runner, not for manual user step-through.

Return Format

Return:

  1. Completed pass work
  2. Evidence
  3. Files or Ghidra artifacts changed
  4. Blockers
  5. Continuation tasks for the next pass if applicable
