Pretty bad IMHO.

I was actually waiting for the NEO-CD to arrive before i got mine,but when i saw the times-i went for the cart system.
The older titles,(where the whole game s loaded in one go at the beginning) are ok,but i hated playing the (newer)fighting games on that thing.
You are as long waiting as you are playing...
And the CDZ didn't really make a change.
That and some missing background sounds(In SS1) killed the machine for me.
It has it's fans here,though,and there is also the 'price' issue... smirk
