The 5200 was never sold in Europe (at least officially).
Nevertheless, I've recently downloaded the the emulator & a few games.
And this is no wonder why it failed.
Most games were oldies from the venerable 2600 with slight improvements.
The 5200 is THE perfect example of the strategic mistakes made by ATARI.
I just wanted to add that.....I'm really glad to join this website dedicated to ATARI.
I got my 2600 when I was 11 (in 1981...) and later a 800XL.
