Now go up to where the long-range trainer is. Make it so that they are off-screen from you, but so that if you walked one tile towards them they would see you. Save right on that spot.
4) Walk one tile towards the trainer so that they see you. At the same time, hold start. If you do it right, the menu will pop up. (If the trainer battles you, soft reset and go again from where you saved. Also, make sure you have actually walked towards them and haven't just opened the menu). In the menu, go to Pokemon, select the one with fly and fly to where another trainer you can battle is. (If you have done it right, an exclamation mark will appear above the trainer when the fly animation happens).
5) Now your menu will be disabled temporarily. Battle the trainer you have left that you can battle. Make sure that they have to walk at least one tile to get to you, or the game will crash. (If there are no trainers you can battle, when in front of the long-range trainer, fly to the Pokemon league, go on the pc, switch to a different box (re-enabling your menu), go into victory road, use strength on a boulder, push it, then battle a wild Pokemon).
