I also have ordered to mini classic
There are some mistakes in the Atari XL version.
-No Parachute go in the tree.
-The Shark doesn't show his face (except when the player die)
-The screen doesn't update like the original, when there are 1 parachute in 2 or 3 different range, the update is done at the same time. You can hear clearly with the sounds that it's not a G&W, there is only 1 sound. Doesn't sound G&W
I also plan to do a colored version with a beautiful copper and funny sounds when the parachute go in the tree etc
