Hi! I can't figure this one out. Right now, most ports of AdvSkel65 appear to be working, but the two Apple2enh ports are giving me the monitor at startup. :( The 64k version used to work, but the 128k version was giving me the monitor at a location used by a Cubbyhole stub. Right now, it seems that the monitor is showing a location in the main program. I think this is happening during a call to the ProDOS OPEN function. I attached the code for the OPEN code, the file-parsing code and the code that reads the files into memory. BTW, I'm using ProDOSi to access the file system. Thank you.
