Yeah, I'd be surprised if anything other than LOS/LPW/Monitor would work on LisaEm.
It might work if a ROM is used, but even then, a very small possibility. For sure, it's highly unlikely to work at all ROMless.

45/47 usually indicate an unhandled exception. Since the ROM fills all RAM with 0xFFFFFFFF, likely what's happened is that it tried to load a sector that it couldn't load (or was the wrong sector number) and would up hitting an exception that had executed junk RAM.
