Works perfectly with Desmume.
Starting game, fighting tutorial battles, saving, turning off and on again and loading. All fine.
iDeaS runs it - but without sound and extremely slow-motion'd.
Trying to load it with Nocash results in a strange light blue japanese textbox.
As expected, my R4 can't do shit.
I have both standard firmware and YSMenu on it.
Standard Firmware has instant-whitescreen.
YSmenu displays "Error -4".
I don't have wood on it.
Up to now YSMenu was able to run everything except Jump Ultimate Stars, which runs fine on standard Firmware, so I never bothered to put Wood on it.
Anyway, other people are reporting that it doesn't run on Wood anyway.
Seems like I'll just chill and play the japanese version on my PC until the game's released in the EU and I get my legal copy. Even though I'm really poor, this game'll probably be worth it.
Edit:
I just installed wood for the sole purpose of trying it out, and after tinkering with it a while it seems that the game will run if you turn off ingame soft reset in wood's settings.
Maybe there's some further hindrance later on, but this will at least get the game running.
Edit2:
Started, saved, turned off and on, loaded. Fine.
@the guy who doesn't get experience:
As far as I know during the first part of the game, which is a tutorial, you do not get any XP.
Not sure on it, though, I'm only 5 minutes into it myself.
