This library talks to a KFCA node through ACIO and implements the sdvxio API of BT5.
Thus, it allows you to use a KFCA device board with *any* version of SDVX that is supported by BT5.

# Setup
* Rename sdvxio-kfca.dll to sdvxio.dll.
* Ensure that your gamestart.bat actually injects the appropriate sdvxhook dll,
for example:
```
launcher -K iidxhook2.dll soundvoltex.dll ...*
```
* sdvxio-kfca expects a KFCA device on COM3 by default
* You can change the port by settings the SDVXIO_KFCA_PORT envvar
* If there is also an ICCA device on the same ACIO bus, it cannot be used with eamio-icca at this time
* Please connect any additional acio devices to their own port (ex: SDVX5 expects an ICCA by itself on COM2)
