Can someone explain why I can't play Virtual Console games on the Wii U Gamepad?

That's why I'm suggesting they don't take the easy way out and PORT emulators, rather remake them to work native to WiiU.

I know, and I'm saying that they're looking into it, but that doing so will mean once again tinkering and testing with the emulator for each and every game, which takes time and (more importantly) money.

The original emulation on the Wii also had faults. they can usually update it at any time.

That being said, a console emulator on a console would most likely be using VSYNC emulation, in which case, the only difference is the amount of clock cycles between each screen refresh (since the CPU instruction sets between Wii and WiiU CPUs are backward compat). It would be relatively easy to design the already existing emulators because a batch of processing at each VSYNC, followed by pushing the CPU into a looped/sleep state until the following interrupt.

Of course, there would be some cosmetics involved due to diffwerence in timing between the CPU and PPU, but that should have already been resolved with a simple ration pause timer on the Wii version, and would only require some kind of integer change (if it was done correctly).

so it can be done before launch

We can only hope...
