This is as far as I cared to optimize my run of Xandra no Daiboken (Whirlo in Europe). At 135,037 frames, it's about a half-minute slower than the record posted on Nicovideo, but at least I offer an input file! :)
I welcome you to optimize my run. If you share this video or your result anywhere, I would really appreciate a little credit for the work I put in getting to this point.
Thanks, and enjoy!
