It crashed into the post-true route stuff, I don't know how to get around the crashing (it might be possible, I'd imagine the PC version is more stable than the PSP fan translation, I might even have accidentally used an old version of it) but since I reached the main ending, I guess it's time to move onto Ever17.
Awesome story though, although lots of interesting elements are in (later released) games. Not sure what's original and what the true origin of plot points and tropes and stuff are. Whatever. I just wish it didn't crash so I got to see more Okuhiko suffering :(
