As to the save questions, all of your save data apart from any txt files with battle cards is in the file sauvegard.dat which is in the crazy party folder (if you haven't created any decs in text and just used the in built deck builder all of your decks are in there too).
Just make sure that file goes into any crazy party install and you'll be fine.
Since the file is created when you make a profile (or possibly when you run the game for the first time), you can just download the zip file of the latest update and replace all the game files no problem.
You can also download a fresh zip, bang the sauvegard.dat file in there and have your saved game on multiple machines (I've played ALMOST every beta from 41 onwards, across three different machines and both sides of the atlantic with the same save file, which is of course also backed up).
Hth.
@Phantom flutist (love the name it is possible to get 20 points on the aquarium, though you need to go fairly quickly. I find using diagonals to insure that I'm progressing onward enough to reach all the bad helps there.
If I remember rightly the unlockable for that is just another safety deposit box, though I could be wrong as I haven't been through the castle since beta 51.
@Bookrage, crazy party is awesome. I haven't actually played any of the gba marrio games, since it seemed a bit pointless to get games for my gba (or my gba player at least), that I still have on my snes. I do know Nintendo have a habbit of updating their music though, a shame these days the only way to play 16 bit style games is with an inaccessible menu interface on the wii or dodgy emulation software on the pc, hence why I still have a Snes and indeed a Gba player,(I'm a huge mega man and Metroid fan).
As regards your second point, when finding an object from top down you have two choices, if it is either north or south of you it's best to center it in the stereo field and then north or south straight.
East or west is a little harder since you need to go n or s until you hear the object change pitch and then run immediately towards it.
As to the race the turtle game, I'd advise try tapping the arrows quickly at first and making sure youdon't overshoot, only when your used to the beacon sounds should you try to hold them, actually I believe they are easier now that you get an indication when a turn in the track is coming up rather than previously where you just got tone at the immediate points you needed to turn. Going off the path is bad on the forst because you slow down on the leaves, and on the beach you plop into the water which obviously isn't good. later on you even have lava or thorns to deal with so it's wise to get used to staying on track.
Escort the duck is tough. What I usually do is get ahead of the duck, then nip east or west when I hear an item, if I can't immediately track it down by the time the duck gets to me I give up and race on, there are plenty of items even if you can't quite grab them all.
I really like the suggestion about duel type stadiums. The stadium types were created back when you could really only have decks of one type, it'd be cool to have more varied opponents to fight against, admittedly, most of the existing opponents have two types, eg, the slapping witch has normal or dark type, but it'd be nice to make it official, and if there weren't enough cards to distribute in the new stadiums you could always just play for gems.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
