GBC ROMs lagging in VBA

[Code-E]

I've been using Virtualboy Advance for about a year now. Recently, I have discovered some issues while playing some Gameboy Color games. Several ROMs I've downloaded either lag or have small graphic errors. At first I thought this was a problem with the roms themselves until I played them on another emulator and they all worked just fine. I haven't had this problem (thus far at least) with original Gameboy or GBA roms in VBA. I need VBA to remove layers so I can rip sprites easier.

Does anyone know how to fix these errors in Virtualboy Advance or know of any other Gameboy/Color emulators that can remove layers? Any help is much appreciated.
