You keep ignoring my hypothetical cart with a socket. Its the same amount of work, the time consuming part is the soldering etc - not flashing the rom. I wouldnt be using anything, there would be no code on the cart, someone can run their own code or a repro or anything else. The end user can then do what ever the like. But I would charge exactly the same price for the labour - obviously there is no selling of the rom/translation.
In your own post you have just said burning the eprom takes a fraction of the time - which is my point, its not the part being charged for, its the labour (again, I am not talking about the sites making stupid money from repros - just the example of people asking me to do the work for them).
Also, what website? I do not have a website.....?
