A report on The Register today purports to reveal that the Big N are tweaking the innards of the Wii console in order to counter mod chips working with the system.
Taiwanese retailers apparently told DigiTimes that the system is being altered making it nigh-on impossible to add in a mod chip without damaging the console. The latest iterations of the console apparently sport a modified motherboard which make it much harder for modders to 'open up' the hardware using current methods.
The most common use for mod chips is to allow the playing of games duplicated via DVD R/RW media, mod chops navigating on-board protection and aiding those pirating games. Those defending mod chips, however, cite that the chips enable legitimate backing up software - making this a contentious issue.
Nintendo have been fairly creative in their battle to slow the system modders in the past, the GameCube, for example, read discs commencing from the outside, rather than the inside, thereby rendering DVDs created in the standard fashion useless.
