Someone went to the trouble of developing and marketing a C=64 in hardware and you are criticising it?! Our Amigas and C=64's and other such toys will not last forever. And while this toy is limited, it is much more satisfying than those Windows 95 remakes of classic Atari games I saw a few years back.
So embrace and hack (er, extend). Maybe more good, and hopefully better, stuff will come out in the future. I mean, just imagine a hackable Amiga 1200 inside of a joystick.
