Research direction

Start by reproducing the slowdown in Tetrisphere (USA).z64 using the reported MD5 on Windows 11 with the listed hardware. No source file, test, or entry point is identified, so the work is to locate the relevant timing or emulation path, determine what causes the random slowdown, and verify that gameplay remains at a consistent speed.
