Are you sure the download completely finished before you copied the files across? And make sure you create a new folder for the files, don't merge them with your existing install.

There's no 100% category, but there is All Brushes and Top Dog (All Achievements). As for routes there's no detailed guide or route map for NG Any%. I'd recommend reading through Cyd's notes (www.speedrun.com/Okami/guide/k5lda) while watching his PB (www.speedrun.com/Okami/run/z5ow8wey).

NG Any% would probably be 4-5 hours long on your first few attempts. It's an enjoyable run though, I'm learning it right now as well. PC is the fastest version of the game for NG categories, the major glitch that's patched on this version (KT Jump) is only relevant to NG+.

Would it be possible to choose which flag is displayed next to your name on the leaderboard? My profile shows the flag of my county and the leaderboard shows the English flag, but I'd much prefer both to show the Union Jack instead. Unfortunately, I can't choose United Kingdom as my country on my profile without also specifying that I'm from England.
