I see a bunch of runs, but none have the "emu" suffix. Is everyone just into consoles or do you have to play it legit

it is okay to made a only Emulator category i think

Emulators are banned as they are inaccurate

It's been a while since I've played on my PS2 but what do you mean inaccurate?
Faster load times?
If so, fair enough, although from the little I've seen, cases like that just end in their own category.

Dolphin tends to have small gameplay inaccuracies scattered throughout and the faster loading would make score screens load faster too (which do count towards in-game time).

You're free to run on emulator and just not submit to the boards, but we prefer to not have an unofficial version be the fastest way to play or making seperate official boards for said unofficial version.
