ignoring this gen (because i know no one with a PS3 and haven't seen any games running on any 360s) the longest load times i have encountered have been games on the PS1, and i had timesplitters2 for my gamecube which was perfectly fast enough, with the exception of mapmaker; if i totally filled the memory bar up making a map then it would usually take about 20 secs to load when playing... but sometimes if i messed around with the tiles i think i managed to get a tiny bit more than the allowed memory, which sometimes meant it didn't load at all (left t for 10 mins and nothing happened) and occasionally i made a map that takes almost 5 minutes to load.
if i still have those maps on my memory card (unnoficial GC mem card might have been formatted) i might try them on the Wii and see if it can load the maps faster. (i doubt it but i may as well try)
