Does anyone have any information or insight on how the ISA comms link card communicates with the Pro Action Replay?I have a document that briefly explains the commands the caetla uses for communication, but it doesnt explain exactly how this is achieved electronically, or am I missing the point. I have lots of AR carts and the comms link card myself but no ISA equipped PC to install it in so cant even monitor it.I briefly recall a thread in the past where the feasibility of a USB interface using an MCU or FPGA was discussed but it didnt go any further.Cheers

You can still understand the hardware interface and protocol through these: http://cgfm2.emuviews.com/sat/comminfo.txt http://cgfm2.emuviews.com/new/psx-gf.png
