I have a softmodded Wii 4.3U. Several months ago I created a region free wad of japanese version of the game, but I can't prove in my console because I don't have any classic controller or gamecube controller (One day if I might prove it). I want to know if it's allowed.
In portable consoles, the emulators are usually allowed, as they have no advantages in terms of loading times to play on a real console. On the desktop some PS1/NES/SNES titles are also usually allowed to use, but more recents systems like PS2 / Wii / GC / PS Usually are banned the use of emulators, in some cases until USB/SD loaders because of those methods tend to run / load faster and have less lag than the original hardware. Let's also take into account that the video capture devices in the portable consoles usually have a very high cost, hundreds of dollars only for saying "to be competitive in this game". It is a rather high cost and that not all speedrunners are going to obtain, not easily.
