The saves from kagura games ver might be compatible with EX ver. At least, with some modifications you can get EX to load the save and your data is seemingly all there. (I haven't actually tested that you can enter EX content from an old save as-is though.)
So I looked into putting together a build for people who want to try out the raw EX from their kagura ver save, where as much as the kagura games version as possible is merged into EX.
The translated UI images were easy to merge.
The translations also seemingly can be merged with a simple script, although I'm not completely sure there won't be any unforeseen issues with that.
The problem is with the text, though.
With a little modification to avoid screwing up the japanese text, the detour hack posted earlier gets the english text to render right.
But, the english text is just too big for the message window. The Kagura script gets cut off all the time.
The best hack solution I can think of is to downscale all the letters in the image fonts and then adjust the spacing accordingly.
It might work but it would be tedious and ugly, and then there is the issue of characters that overlap between the two scripts.
I might end up trying it, if I do and I can get all the translations merged then I'll post it.
Anyway if you want to try out the completely raw EX version from your save:
(In a hex editor or make your own script if you want)
- Trim the end of the file so that it has the same length as the EX ver saves
- Replace 0x00 - 0x09 of the file with [45 57 57 2e 2e 30 31 2e 30 31] (the string "EWW..01.01")
- Get the SHA256 hash of offset 0x52 to the end of the file.
- Replace 0x0e to 0x40 of the save with the hash as a string. (ascii and MUST BE IN LOWERCASE)
