If you cannot find a job that will pay you for using the software that you
have learned to use, then why do you need to have that software? The only
software that you need is that for home use, and you get that software when
you buy your PC.

Hardly. I imagine that you can package a decent CPU with lots of ROM and
some RAM within a PII cartridge easily. Looking at the modern mobile phones,
it can probably be much less than that.

So, do not make it EPROM. The entire ROM (with its contents) can be printed
in the silicon.

If you consider again that the CPU I'm talking about is printed together
with ROM and RAM, then it might be difficult to "reprogram" it. Your only
option would be to get a CPU with the same architecture and instruction set,
which may not be available. The latter can be made harder if the
architecture and the instruction set of the super dongles changes for each
game. Then you would have to buy either a very high performance generic
"emulator", which will cost a lot more than a few games, or buy a "blank"
super-dongle for each game, which will probably cost more than the game
itself.

Right. Which forces you to spend money and effort, which is a lot less
comfortable than downloading a cracked game. Do you think that the number of
"cracked" sat-TV receivers is comparable with the number of "regular"
receivers?
