You need the HM5 Flash.
to learn flash you should have pokiemon up to 10
use flash in the cave and it will be a lot easier. if you already did, then figure it out. try different ladders
The HM's that are in leafgreen are: Cut, Fly, Surf, Strength, Flash, Rock Smash, Waterfall.
The Pokemon are Bulbasaur, Ivysaur,Venusaur, Geodude, Abra that's all I know!
Go to route 2 and use cut on the tree go north to a big building go inside talk to the scientist say YES and you get the HM flash.
well first you need flash and you go to the rock tunnel and use flash and after you make it through the rock tunnel then you walk down the path and then you are in lavender town!
You would have to but a flash card for the GBA and then put a hacked rom on the flash card to play.
