I am pretty sure that you just click the Pokemon you want to teach the move, click attach and choose the t m.
It doesn't matter since Pokemon indigo doesnt work anymore, but you go to your Pokemon select screen, choose the Pokemon you want to teach the TM to, and choose teach TM under the moves screen
just choose the TM you want to teach and hit use then choose a Pokemon and delete a move [a Pokemon can learn up to four moves] but what you might be experiencing is maybe your Pokemon can`t learn that type of move
Put in the code for your desired move, teach your Pokemon any TM and it will learn the move you wanted it to learn instead of the original TM.
Sheer cold is a move you can use in the Pokemon games. There is no TM that can teach this move.
TM stands for "Technical Machine." They are used to manually teach a Pokemon a move, provided that it is able to learn that move.
There is no Pokemon indigo
you teach a Pokemon that move or use a TM
Actually it's not a TM. You have to get a move tutor in FireRed or LeafGreen to teach it to a Pokemon.
Tri attack is no longer a TM to teach that move you must find a move tutor that teaches the move in the game.
yes,let the Pokemon you want to lean a move and teach it
HM's and TM's
You can buy TM's from the shop or by defeating gym leaders.
