In Slateport, there is a lady who asks you to make some medicine using a berry crush machine that she installed apparently in the pokemon center.....

Maybe ive got this wrong but i cant find the berry crush machine.

Can someone tell me the exact location (like walk to the pokecenter, go upstairs and its the lady on the right or whatever)
and how im supposed to activate and use this thing?

thanks!

I have been wondering the same thing and i have played emerald 4 times with around 100 hours each and i cant find it.

It's a game played with the Wireless Adapter with FRLG, upstairs in the Pokemon Center, right counter. (In Ruby and Sapphire, no such game exists. The upstairs Pokemon Center is near identical to GSC.)

I never got a chance to play it, but I believe you're supposed to mash the A button a lot, and if you mash it at the same time as your friend(s), you get bonus points. (That's what my FRLG guide says, anyway.)

That sucks i dont have a wireless adapter. For some reason my Fire Red didnt come with one.

It was a limited edition thing that only happened for a couple of months. Since I preordered my LG and got it the day it came out (Sep 7 or 9 or something), mine did come with one. I later purchased a second one at Gamestop; they're relatively inexpensive.

ive been looking for the crush master too, but when i first started my game, im almost positive i ran into him, but i cant remember when it was...

I didn't know it was a limited edition because I remembered seeing them with the wireless adapter but I didn't get mine until around a year after it came out so thats probably why.

my friend had two saphirres and gave them away and he gave one to me so i dont have a wireless addapter but my friend has ruby and i have a normal(wire) addapter. will that work?

Ruby and Sapphire are not compatible with the Wireless Adapter.
