I'm curious, how did the hardware present itself? It couldn't have been an Amiga Zorro card since it would've been impossible to get that into a PC. Did it connect over a serial or parallel port?

I recall it being some custom ISA card with connectors on the back. The emulation software had drivers that interfaced directly with the card.

Interesting! So they were able to port the hardware but not the software for whatever reason?

If it's what I suspect it might be, it was probably a generic IO card with maybe a bunch of 8255 PIOs on.
