[Coco] CoCo Cassette Relay (Remote)

[Luis Antoniosi (CoCoDemus)]

You need a DW ROM pak. Then it will load them all.

Every game that puts coco back to ram mode and recopies all the rom will
screw the DW in RAM.

I easily modified a Typing Tutor rom pack and installed a 2764 with the DW3
rom on it.
