Thanks for the reply! I tried using PGMPhysGCPtr2GCPhys, but the returned value always seems to yield an error i.e. RT_SUCCESS(rc) never holds. I do not see what I am doing wrong.
Also, I tried using PGMR3DbgWriteGCPtr and I also have the same problem. Perhaps its because of the flags I am passing. Which flags should I pass to this function? Could you please provide a working example if possible on how to properly call these functions? Thanks for your helpful advice!
