As I recall, you don't need to apply the patch. All you need to do is give the patch the same name as the rom and place both the renamed patch and the unpatched rom in the same folder as the emulator. VBA has a function that applies patches automatically.
Note that it has to be the unpatched rom you place in the VBA folder. If you patched the rom already you need a fresh copy.
