It is crucial to clarify that downloading a copyrighted Wii game from the internet is illegal in most jurisdictions unless you own an original physical copy of that exact game and are downloading it as a backup for personal use—a right that is often narrowly defined and varies by country (e.g., the U.S. DMCA prohibits circumventing copy protection even for backups). Downloading a "highly compressed" repack from a third-party source is almost always copyright infringement, as you are not creating the backup from your own disc.
Nintendo, in particular, aggressively pursues takedowns of ROM and ISO distribution sites. While older Wii games are no longer in mass production, they remain under active copyright protection (typically 70–95 years from publication). The company also sells re-releases and ports on newer platforms like the Switch, so "abandonware" arguments generally do not hold up legally.
