This is probably a wild goose chase since people have asked help for similar issues, yet have gotten no answers, but it's worth trying.
A friend and I wants to translate Lovely X Cation 2 (https://vndb.org/v10288)
It uses KRKR2 alongside a bunch of in-home plugins/adjustments (I don't know if that matters or if true)
We have tried all the public tools we could humanely get our hands on to no avail. Either the outputted files (the ones that does matter) comes out as complete gibbers, or we get returned the following error: Expected "#01" at position 0x17 but saw "#80".
