I'm super curious, so would this also work with nvpktool to use this without scanning in the dot codes? I'm currently trying to figure that out in hopes of localizing the events. I'd really appreciate a reply to see if it's been done already!!
Not 100% sure what you're asking but nvpktool let's you disassemble the dot codes, you could then localise them by replacing the text and then rebuilding the dot code. You'll still need to scan in the new dot code.
I have localised the Battle e Series 2 cards and done a bit of work with the Regi doll card but I've been a bit busy to complete it.
