Of course the ideal solution would be an emulator with tape loading
emulation, but I don't know if one exists.

Did you try simply BRUNning the files from a normally booted DOS or
ProDOS? That might work at least well enough for you to get a start
screen, as long as the code doesn't clobber DOS or ProDOS itself.

You can also try BLOADing the files, then resetting the Apple without
loading an operating System (on a //e emulator: CTRL-OPENAPPLE-RESET
followed by CTRL-RESET). Then CALL the start address. This way the
Program is free to use the DOS area once started and can't get confused
by the changed I/O vectors of a loaded operating system.

This won't help with programs that load directly into the area where DOS
or ProDOS normally resides, but I'd assume that since most tapes are
from an era when many people still had less then 48K RAM, few will load
into the memory area where DOS resides on a 48K+ system. In the case of
ProDOS, using LOADER.SYSTEM instead of BASIC.SYSTEM might help, as it
frees some RAM if I remember correctly.

If the program is a multi loader, you will have to hack it to load the
other parts from Disk instead of from tape.
