Rock Climb

But it is just a waste to win a game like that.
Anyway I give you the code which gives you all TM and HM.

Press l+r to activate.

Really, you should go through the game clean and then use your cute little codes.

But if you wanna get rock climb the legit way, on the route to Snowpoint City, you'll see a lot of houses, one house has a Hiker in it and if you talk to him, he'll say something about loosing his HM, so go outside and somewhere north (near) his house is the HM, go talk to him again and he'll let you keep it and he'll give you an Icicle Plate.

OK so you got INTO the problem by using cheats and NOW you're trying to get out of it by useing MORE cheats? JUST PLAY THE GAME!! Rock Climb is in the Solaceon Ruins, bottom floor.
