This library drives a "legacy" ezusb IO board, also known as C02 IO, and implements the iidxio API of BT5. Thus, it allows you to use this IO board with any version of IIDX that is supported by BT5.

Setup

• Rename iidxio-ezusb.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 ...*

• Before running the game, you have to flash a set of binaries to your IO board (base firmware and FPGA). The iidxio-ezusb.dll does NOT take care of this and only drives the hardware during gameplay. The binary images required are not included with BT5.
• Use the ezusb-tool.exe binary included in the tools sub-package to flash the appropriate ezusb base firmware. Once the firmware is flashed successfully, the status LEDs on the side of the board should show a blinking pattern.
• Use the ezusb-iidx-fpga-flash.exe binary to flash the appropriate FPGA binary dump to the FPGA.
• There is a script called ezusb-boot.bat which combines the two steps above and can be integrated into the startup process of a dedicated setup.
• If you ignore these steps, you will either run into errors or parts of the IO board won't work (e.g. lights).
