dispatch_stats TCP command: g_dispatch_static_hits incremented on every binary-search hit in generated dispatch; exposed alongside miss_total and miss_unique so static coverage ratio is measurable numerically. fast_boot = true in [runtime]: first launch runs BIOS normally (logos visible) and captures full system state at game handoff to fast_boot_<bios_cksum>_<entry_pc>.bin adjacent to the BIOS. Every subsequent launch restores the snapshot and dispatches directly to the game entry PC — no BIOS execution, instant start. Snapshot captures: CPU (gpr/hi/lo/cop0/gte), RAM (2 MB), scratchpad, dirty-RAM bitmap, i_stat/i_mask, timer state. GPU/SPU/VRAM not included (game reinitialises). Display-disabled vblanks now clear SDL to black so the window never shows OS-background white during game crt0 setup. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
