Press the red squares to turn them into green squares, then when you are satisfied with the combination press save. Copy the code. When you have the code you can reset, and load your code to get the combination back.
So I had a dream last night about binary save codes, so I made a saving system to test it. Lo and behold, it works! In my upcoming game "Hood" There will be many items you can collect, the way I will keep track of that is using a list. 1 means you have the item 0 means you don't. So when saving instead of needing to copy a code like 10011011011100, you can just copy the code 9948 Pretty Nifty, I don't know how standardized this is, but I don't think I've ever seen it before, and I am pretty proud of it.
