All of this, but especially the bolded bit. The game just feels mean. I beat it on normal, but I don't think I'd ever want to replay it. By far my least favorite of the Tengo Project games.
If the audio tracks are in the wrong order, you can edit the .cue file. They're just text files, so you can open them in any text editor, even plain Notepad. I had to fiddle with Neo Turf Masters since the courses had the wrong music.
I threw it on my SD loader. Not sure when I'll actually get around to trying it. Funny how the SD loader only got support for the game in the latest firmware which came out in mid-October.
