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.
