I sound a bit stupid now, as I usually answer the questions, but I've got..

For starters The Berry Masters Wife- Tell her these sayings to get the desired berry:

Super Hustle- Belue
Challenge Contest- Pamtre
Cool Latios- Durin (haven't tried this one yet, should work)

For the Mago and Aguav go see the girl walking around at the end of rt 120 by the berry bed. She gives you different berries each day, it shouldn't take long for a Mago, but a little while for an Aguav.

I haven't even heard of the other ones.

I need help with mystery event- can you help me?

Hllo, I know ehre to get some of the berries:

13. Mago: If your user ID ends in 2 or 7, then go down the road east of fortree until you find a woman next to a patch of berry-dirt.

Talk to her, it doesn't matter if you say yes or no, u get a mago! If you don't have that ID number..

Well, get one off a friend
(P.S, if your ID is 0 or 5, you get a figy, if it's 1 or 6, you get a wiki, if its 3 or 8 you get an 14. AGUAV!!!!!!!!!!!, and if it's 4 or 9 you get iapapa......)

32. Pamtre: Defeat Elite four and champion, then go back to the berry master's wife (west of mauville, over water and through grass), she asks you for a phrase.

Reply, CHALLENGE CONTEST. She'll give you a pamtre berry! Note: You can only get one, so plant it and grow more!

Double Note: Water it every hour, otherwise it will only grow 1! Min: 1 Max 2 :0
34. Durin: Catch or find LATIOS, so it's in you pokedex. Go to berry master's wife and tell her COOL LATIOS. You get a durin berry! Note: Same rules apply to pamtre berry!

35. Belue: Go to berry master's wife and say SUPER HUSTLE. She gives you a belue berry!

Note: Same rules apply todurin and pamtre berry. :(
(P.S 31. Spelon=GREAT BATTLE (BM'sW) 34. Watmel=OVERWHELMING LATIAS (Find or catch Latias, BM'sW)
Hurray! 5 new berries under your belt!

So I don't know about berries 36+, but I have a suspicion that you might need cheats :(

Hope I helped!

I'm sorry but I will only answer part of your question.Okay,go to the berry master's house.

Talk to the lady.She will want you to say a phrase.

And now if you type in a certain phrase(code) she will give you a berry(could be a rare one!).I only know one code and that is"cool latios(latias)....I forgot which one.

SORRY!And you will get a rare berry.I forgot which one,do I have short term memory?The Ganlon berry Jirachi is holding.

So get the bonus disc.By the way,almost every single berry you mentioned is rare and needs a code,and I'm not talkin about Action Replay or any other thingy here.

P.S.Now I shall be searchin for codes for me and I might tell you if you ask for berry codes.

Oh boy,it would be life threatening to you if you tried to ask another question!

Well, on Sapphire you get a Jirachi and it is holding a Ganlon Berry,and on Ruby you get a Jirachi and its holding a Salac Berry.

Sorry, I don't have the rest.
