Need locations for a few items.

Where can I find the moves Calm mind (tm4) and Earthquake (tm27) in Leaf Green?
Also where do I get the master ball?

I have another question too.
Today while playing my recently restarted leaf green, the game froze while I was saving, so I turned it off. Then I turned it back on and it said something like:"the save file is corrupted", "previous save file will be loaded". Is there something wrong with the game? It's not a fake game and I've never used any cheating devices. I never encountered any glitches on my previous file (168h of gameplay).

I think Sabrina gives you Calm Mind once you defeat her.

As for Earthquake, I think Giovanni gives you as well, once you defeat him.

Nothing is wrong.It's just an error while saving, these things happen when u accidently pull out the game. It happened to me

If you have a fake game (like I did before), if you turn it off while you're saving, the save file will actually be deleted and there will be no previous loads.
