I also plan to eventually add more to this menu.
I do plan to release some sample code for calling natives from a webkit payload in the near future. The payload will also enable debug settings and spoof your firmware version to 9.99. Everything is done within the payload, there is no outside tool. However, the menu remains extremely simple because of the memory and coding limitations set forth by the code injection method I use to make this work at all. I have added a few thing since then as well as rewritten the entire thing to call natives by hash so as to not have to change a hundred addresses for a different game region (stupid decision to call them by address in the first place, I know). I'm sure many of you saw the preview for this back in December.
