The disc and tape loading in Minus/4 are done by simulating the hardware directly, not by patching or detecting ROM calls. So it should all work as per a plus/4. Not that its perfect of course, it has limited I/O functions. Normal Load should work, no turbo loaders as I don't simulate the $01 address line, only the DMA byte port address. (this should be enough).
