For the GBA version, what emulators are allowed? and what should their settings be?

Hey! I don't run the GBA categories, but hopefully I can still help.

There seems to be a GBA run on the boards already using Emu. I would assume just from past experience that it is VBA (Visual Boy Advance) as it seems to be one of the most popular. For the sake of accessibility emu runs for the game are accepted, however will be held to a higher degree of scrutiny when verified to ensure fairness. No speedhacks or other settings that improve the performance of gameplay above the Hardware's original capabilities. These rules regarding the inclusivity may be subject to change in the future as things advance, however that seems to be the state we are at currently.
