OK so this is out and it sort-of works on GEN-D2 (fixed), and maybe GEN-D3 final (original ISO?). There are several points where the game freezes:
1. When you try to use the screenshot function (this was in KB3)
2. When you try to install the install data
3. A rooftop event that I haven't got to yet, but all the Japanese blogs mention it freezing there
Does this sound like a bad dump, or copy-protection, or what? Great game, by the way.
