1. ▌
   Profiling · grarak

   Profile DSVita on the Linux ARM test box — flat perf profiles, per-instruction annotation of native functions and inside JIT blocks (jitdump), and A/B throughput benchmarking. Use when asked to profile, find hotspots, annotate, or measure a performance change.

   Run Local · grarak

   Run DSVita locally on the dev machine under qemu-arm and take screenshots — use when asked to launch the emulator locally, boot a rom for a quick correctness check, open the menu UI, or capture what the local emulator window shows.

   Inst Trace · grarak

   Capture, decode, and diff binary per-instruction traces to localize emulation bugs — use when debugging an interpreter-vs-jit divergence, a game hang/crash/corruption, wrong register values, or when asked to trace-diff two engine configurations.

4. ▌
   Run On Testbox · grarak

   Deploy and run DSVita on the remote ARM test box (raspberry pi class, native armhf speed) — use when asked to test a build on the pi/test box, run a game at real speed, take remote screenshots, or inject button presses remotely.

   Gen Interp Tables · grarak

   Regenerate the interpreter's flat dispatch tables from the disassembler lookup tables — use after adding/renaming an interpreter handler, changing the disassembler table layout, or when the interpreter table drifts from the jit decode.
