Awesome game. Thanks.

[The Ultimate Intellivision Flashback]

Thanks. Only thing is, I want to use the newest retropie (4.1) from the official site. How does the 3.5 zip file affect those newer 4.1 files? Is it safe to overwrite the 4.1 files with the 3.5 files in the zip, or is that a bad idea? I'd hate to mess up a brand new installation of retropie. Is there some new stuff in the 4.1 files that might get overwritten by older copies?

I am curious about this as well. The hack files were last updated for 3.2.1. Has anybody used them on the newest 4.1 retropie? I am getting ready to make a couple of these for Christmas gifts.
