this "eventually" is at least 10 years or more away.
emulation in the ladder is only going to be justifiable when cheap level PCs can run the game perfectly and finding working GC/Wii consoles becomes near impossible and discs die due to disc rot.
and even in this event, the rules allow USB loaders and SD cards to get past the dead discs. consoles's internals last a long time.
we'll have this discussion in the 2030s. for now forget about emulation on ladders.
(also, this site's code is too old and convoluted to add new ladders. it's never getting new ladders. we have to wait for a brand new site)
