I made it work once but didn't keep track of how I did it.

So you upload your Chara Card onto the desktop or where ever, overlay your screenshot and save it. Put it in your Date file, fire up the game, find her and load her ... she's been corrupted.

I'm convinced the problem is in the "save as" feature of PhotoShop and Paint.net. I'd like to overlay a second pose to the card by way of an Alpha Mask. Or grab a screenshot and overlay it onto the card. No tamale.

Thanks in advance for any suggestions.

Have you tried using WaifuRipper?

Create the image you want, then open WaifuRipper, load the chara card, then click on Snowflake, select your screenshot and it will do the trick.

The png file holds information about the character, you would need a program like Notepad++ to safely copy the information of your screenshot to the chara card, or vice versa.
Baaack then someone made a tutorial on how to do it, but i can't remember now, maybe i can find it if you want to know.

Thanks a million! I know the card holds the code. Once I tried copying the code as the save as. Didn't work.
