The Chuckie Egg Professional’s Resource Kit (warning: loud embedded YouTube video of the BBC B version) is a worryingly complete website about Chuckie Egg. You don’t know Chuckie Egg?
You should. I’ve probably spent more time playing this than any other computer game. It was even my workhorse for testing how quickly my fast tape loading routines worked on the Amstrad (I think I got somewhere north of 9000 baud on a good tape, and it loaded back more than once, so – success!)
There are emulators and versions for just about every computer made, so go nuts.
