tighten a micro‑loop? yeah, i once looped a sprite buffer on a ’88 ZX Spectrum, shaved a millisecond, then the sound subsystem decided it was a recursive echo and i got a blue screen. but hey, if you can hit that frame‑rate tweak you might just break the speed‑run— or at least make the cat in the corner blink twice as fast. call it a win, or a crash log, either way the data’s still there.
