A hook library that can be used with BeatmaniaIIDX games that run the old ezusb
IO board (e.g. 9-13). It allows you to exit the game by pressing Start P1 + 
Start P2 + VEFX + Effect simultaneously. This is very useful if you want an
option to exit back to your desktop without having a keyboard attached.

The exit hook lib must be loaded like any other hook lib you are already
injecting to the game using *inject*. The order for the hook libs is important 
as they are loaded in the order specified for the inject call. The entry in 
the *gamestart.bat* file should look like this:
*inject iidxhook1.dll iidx-ezusb-exit-hook.dll bm2dx.exe ...*

Where iidxhook1 is used for version 9-12. Use iidxhook2 for version 13.
