I removed all old conversions from db because it quickly became confusing when I tried to figure out which ones I don't have yet. I'll just reconvert everything again.
I think I cannot access some images because they are encrypted with a new algorithm which is not supported by the ripping software, and I never worked with encrypted data, so there is nothing I can do.
At the equipment screen when you select an item, the game shows you how stats will be changed after equipping/unequipping. Positive changes are green, negative are red.
And stats that don't change at all are red too, except health. Why? It makes no sense.
