WiiBrew:Piracy
Unauthorized copying (also known as "piracy") discussion is not permitted at WiiBrew. In addition to sharing ROMs (no matter how old), this also includes playing "backups," regardless of how they were obtained, on original hardware. This means no "USB Loader GX" or "Dolphin Emulator Ported to Wii". However, other software related to backups are permitted, such as game modding tools, WAD editors, and tools to obtain backups.
WAD installers are permitted, as long as they have mechanisms to prevent prohibited copies of software from being installed. Drivechips are fine, assuming they are solely used to enable homebrew or fix bricks.
Also, in case it was unclear, linking to ROM download sites is prohibited.
Why?
There are 3 main reasons for this policy.
First, unauthorized copies hurts Nintendo's feelings. If backup players are discussed here, Nintendo will see this as a threat to themselves and be more likely to pursue perceived copyright infringement. While the Wii is no longer being maintained, many Wii hackers have moved on to newer consoles, which Nintendo does maintain, for example, the Nintendo Switch.
Second, many people believe that unauthorized copying is unethical. While many people claim to not be making prohibited copies, by releasing such loaders, prohibited copying becomes more tempting. As SciresM said:
If someone begins using a backup player, they will eventually realize buying games is pointless, and start downloading them instead. To prevent this, discussions on the possibility of performing unauthorized copying must be stayed away from them at all costs.
Third, certain homebrew is questionable in regards to the law. Section 1201 of the DMCA prohibits "circumventing technological protection measures", although this section rarely gets enforced. However, if homebrew suddenly became equivalent to "circumventing technological protection measures", WiiBrew may be taken down.
