It it were possible then it is just a decision, which bunch of 
facilities does one prefer and is any 26bit only needed.

We are where we are, there are two forks, there have been two forks 
for some years now and there will probably continue to be two forks in 
the future. I can't be bothered with all that anymore but I do have 
choices.

I cannot think of any compelling reason why one would want to run 5.20 
in preference to 6.20 on VRPC. If there was a version of VRPC that did 
run OS5 I might use it because I already use OS5 elsewhere. Conversely 
I do not believe OS6.20 is currently available.

There are four variants of rpcemu on my Mac, OS4.04 26bit only, OS4.04 
with the Castle CLib, OS4.39 and OS5.21 demonstrating a complete 
failure of decision making.

Not that I am aware of but as ever there has been plenty of talk.

But why would one want to! Oh, that was the original question.
