Details

Game request.

It seems that a slightly newer game (2004) by the same developer is already supported. The program can extract scenario.xp into several files with a BCS extension. But it seems it then attempts to further extract (or perhaps decrypt?) the BCS files and fails. These files are still encrypted, or at least appear unintelligible to my untrained eye. scenario.zip

Hatsukoi Patch.zip So with my limited programming knowledge, I haven't been able to make much progress. However, I did find out that the BCS files are likely encrypted .csv files (Excel comma delimited workbooks). This is from the partially complete English patch from several years ago, so I would imagine it's easier to figure out the encryption if one has both the end file and the start file? I attached the patch to this post.
