I have just startes on speedruns and I want to now if i can do it on these emulators

from the rules: "Accepted emulators are VBA and VBA-rr. All other emulators are banned."

There is also a rule stating that "All emulators are hidden for this game by default, as all emulators play this game faster than any console can, and therefore do not produce accurate results, or provide fair competition" They will be on the leaderboard, but they will also be hidden unless you click FILTER, EMULATOR, SHOWN. You may or may not care, but I'm just saying.

Also, drastic is an nds emulator and cannot play gba games anyway.
