IIDXIO API implementation with BIO2 driver

This implementation of BT5's iidxio API allows you to use native BIO2 hardware with anything that supports BT5's iidxio API, e.g. all iidxhooks of BT5. Thus, you can play your favorite old IIDX games with the latest generation of hardware.5.

Setup

• Have iidxio-bio2.dll in the same folder as your iidxhookX.dll
• Rename iidxio-bio2.dll to iidxio.dll
• Ensure that your gamestart.bat actually injects the appropriate iidxhook dll, for example:

inject iidxhook3.dll bm2dx.exe ...*

or

launcher -K iidxhook4.dll bm2dx.dll ...*

• This assumes that the BIO2 is already flashed to the correct firmware. The firmware perists once flashed and does not need to be re-flashed after a power cycle.
