... BASIC PEEK command will _always_ read the RAM, so you must write your own small machine code routine. This is not emulator specific, but plus/4 ROM specific.
If you're interested I might post a small code snipplet somewhere (in fact a whole more general help/readme/FAQ file would be better...).
I would advice checking at address $FF76. If it's equal to "Y" then you're dealing with YAPE personally  Other letters may indicate other emu's in the future as it was kind of agreed upon by other authors earlier. Then $FF77 will serve as a special ROM address its value would alter between $55 and $AA after each read attempt but this is not yet implemented (this is the way VICE works IMHO, and considered as a sort of a standard since a while).
