The less-efficient `WaitForVBlank` will now only run while the Wireless Adapter is communicating. This has been written so that, during normal gameplay, you won't lose performance due to an extra jump as the comparison follows right into setting the `swi` and then the function exits immediately afterwards. The only loss over the above two versions are the cycles needed to perform the comparison. The code jumps only while the Wireless Adapter is communicating, but the busy loop tanks performance in that scenario anyway so the cost is negligible.
