Looking specifically for a save just past the arcade games...I'd be playing them until July, hehe. Thanks in advance!
(Game maker apparently used to have dames, but their link no longer seems to work. Something else I found via google looked a bit hinkey...)

I hope that someone will be able to help.

Let me check for you, Murphy.

EDIT: Sorry! I checked and I don't have any saved games!

Eureka! More searching turned this up...has a variety of saves. I don't know that you can extract "all" in once you download, but I picked one of the files approximating where I was in the game, and was able to extract that over. N.B., in your user file, the app data folder may be hidden, and you'll have to go into File Explorer properties of that to un-hide it (including subfolders, etc.)...then you'll 'see' it when you go to extract. The appropriate folder is buried deep, about 7 layers down...Here's the link:

Assuming you're using Windows, just right click the downloaded file and select Extract All from the drop-down menu. Windows can unzip your files where ever you want them to go.

That's quite a find! Don't think I've ever heard of lonebullet.com. They have a lot of good information there including walkthoughs.
