I deleted it because what I had posted was wrong.
I though V- and GND were still common, and they are not.

ANY non-floating reference ICs cannot work like the 317.
All values were calculated with a 22ohm 1/2W 5% resistor
Voltage supplied (V): Test load (V): Output (mA):
6V 4.2V 57.5mA
8.4V 4.2V 57.6mA
4.1V 4.2V 15mA
4.1V 2.8V 56.5mA
8.4V 2.8V 57.4mA
Voltage supplied (V) Test load (V) Output (A)
@ 1ohm
8.15V 2.8V 1.24A
@ (2) 1ohm resistors in parallel = .5ohm
8.15V 2.8V 1.93A
8.15V 4.2V 1.22A
