Genuine high-quality compression of a Wii game like Super Mario Galaxy 2 (original ~4.2 GB) usually results in files around 150 MB – 500 MB using formats like WBFS or compressed RVZ. Be cautious of suspiciously tiny files (e.g., under 50 MB) — they often lack audio, cutscenes, or are fake/malware. For emulation (Dolphin), the RVZ compression format is recommended for quality vs. size.
