- Make handle_vblank strictly increment frame counter (frame++) - Move heavy frame logic (background updates, OAM updates, palette animations, and console stats) to update_frame() on the main thread synchronized with swiWaitForVBlank() - Eliminate 256-byte ARM9 IRQ stack (sp_irq) overflow caused by bg_update and iprintf that was corrupting DTCM stack and causing data aborts - Preserve all playfield entities on game over with top-screen defeat summary and smooth background deceleration Co-authored-by: Antigravity <antigravity@google.com>
