This is an experiment for #63, it doesn't really fit this repository, and is probably only here while it's work in progress.

In this branch, I attempt (successfully so far!) to relocate the NIC MMIO, and install MMIO hooks so we can emulate a virtual NIC, so the real NIC remains fully under our control.

This would allow us to co-exist with networked games. Also games wouldn't be able to terminate our network connection. All of this has huge implications for many use-cases such as:

  • Tunneling of network games or even Xbox Live hooking
  • Debugging network games
  • Streaming files from elsewhere, while a game is running
  • FTP servers while games are running

Similar code could also be used in the future to hook OHCI (USB) or other devices.


// FIXME: The following instruction parser / emulator could be nicer.
// Each case was added when the instruction was ecountered, so
// no actual design went into this code, or parsing anything.

The following code should be illegal!
The fact that we have 2 variations of the same function doesn't help. Someone should refactor this.
