A minimal, strict TJS2 (Kirikiri2 / Kirikiri-Z) bytecode loader and disassembler written in Rust. This tool allows you to inspect, analyze, and decompile compiled TJS2 script files (.tjs).
- Disassemble: Convert binary bytecode into human-readable assembly mnemonics.
- SSA&HLIR: Generate Static Single Assignment (SSA) form or High-Level Intermediate Representation (HLIR) for deep code analysis.
- Decompilation: Attempt to reconstruct high-level TJS2 source code.
- TJS Emitting: Generate an executable TJS script that replays the low-level bytecode logic.
cargo build --release
The binary will be located at ./target/release/tjs2dec.
tjs2dec provides several subcommands depending on the level of detail you need.
To see the raw instructions and constant pools:
tjs2dec disasm Action.tjs
To attempt to recover the original TJS2 source code:
tjs2dec tjs Action.tjs
To dump the Static Single Assignment form (useful for understanding data flow):
tjs2dec ssa Action.tjs
To dump the High-Level IR (HLIR):
tjs2dec ssa --hlir Action.tjs
To create a low-level TJS program that mimics the behavior of the bytecode:
tjs2dec emit-tjs Action.tjs
