Well id say it goes like this
VisualBoy Advance = Slower but higher compatibility
Boycott Advance = Faster but ok compatibility
BatGBA = Faster but bad compatibility (Compared to others)
Mappy VM = Faster/Slower but bad compatibility (Compared to others)
DreamGBA = Faster but lower compatibility
Also id like to note that all other GBA emulators besides VBA can run Worms World Party GBA version VBA cant
Hope that helps
PS: Any mods feel free to change the poll i forgot to add DreamGBA any nice mods wanna add it for me
