Binox released this news a couple of days ago on his DreamEmu Compatibility site:
The secret project that I’ve been working on is a project codenamed HALD. It’s a PCI card that will allow PCs to read GD ROMs and allow fast data transfer to and from the DC via the parallel/expansion port. It would also allow DC – PC networking and possibly access to PC resources if a program was ever written to allow it.
