I've only used visual boy advance for GBA games in general as it's the most solid emulator in my opinion

BizHawk (mGBA) is the most accurate

BizHawk (mGBA) is the emulator i've used for 2 months but visual boy advance i use casually. I do have the official GBA copy of it for my DS and GBA but i don't have a capture card yet (i might try recording on a webcam but the one i have isn't very good nowadays and i do have enough money for a better webcam or maybe even a capture card if i wanted to)

The gameplay and plot are the same as in the original version of Super Mario World for the Super Nintendo Entertainment System.

Yep,Mgba is the best emulator to speedrun Super Mario Advance 2 (And The Other GBA Games).

Hey OpenEmu is an a emulator of consoles incluiding gba
