TNMT for me too.
No arcade in my small town, but the independent video store had a single arcade machine and, for a year or two when I was about 10 or 11, it was turtles - a 4-up cabinet.
Also spent all mine and my friend's spending money on it when we went for a trip to Drayton Manor Park with my parents. Still didn't finish the damn thing.
Played throught it on MAME with my kids a couple of months ago. They liked it too, though it's a lot different when you're not spooling actual 10p's into it.
