Apparently the Rugby League game for the Wii, deson't work on modded Wii's if you buy it or burn it.
Some of the older Wii's with chips like the Wasabi doesn't work with this game.
Rugby League 3 – Retail not working on modded Wii
From the looks of on the games official forum, the game “Rugby League 3″ contains a new type of protection that disables the retail game to work on a modified Wii. A game that is bought, if tried to play on a modified Wii, it will not work.
Apparently, newer chips, and softmods are working fine, which the wasabi chip and some others have been reported to not work.
On the back if the game’s cover it clearly states that “Unauthorized technical modifications to your Wii console may render this game unplayable”.
Clearly, a small game developing company has created a protection system, that big Nintendo themselves could not develop.
