I guess you should wait for the next release of the game :)
you can find him around Kanto after beating the elite4 if you started with bulbasaur
after you beat shadow entei, you wait till 12:00 pm and then talk to ash and gary. ash tells u 2 go 2 the continued part of route thirty-two, and u go there. enter the other side of the route, if u know what I mean, and you'll begin the shadow mewthree level. after u beat it, celebi talks 2 u. u'll have 2 wait till sam updates the game to go further in the story. until then, catch a shadow unknown in the shadow entei level. and train up ur pokemans. =-D
it's wild in kanto after beating the elite four and you chose bulbasaur as your starter Pokemon
keep beating World Axle B2F Cave after you beat the game and if you keep beating it you'll eventually get it
You must have chosen bulbusaur at the beginning of the game and have the pokedex eventually entei will show up when your in grass. If you didn't choose bulbusaur find someone who did get entei, if you have a Pokemon colosseum you get a shadow entei from the game.
To get the shadow Entei in Pokémon Gale of Darkness begin by searching in the Gras. When the shadow is located use mind reader to stop it from getting away.
you can't permanately get entei to stop fleeing, but you can use mean look(crobat and golbat and jynx can learn it),fight entei with a Pokemon that has shadow tag(wynaut and wobbufet)or fight entei with a Pokemon with arena trap (diglett and dugtrio,but has to be from diglett's cave,which is in kanto)
You cant get entei in any of the hoen region games. Entei is a Johto region Pokemon
you c'ant capture entei in Pokemon ruby do you understand
There is Entei where you go to MT. Battle for the first time and go all the way to ten and Face off with Dakim and capture Entei with at least a Great Ball but HP must be in red but if he faints countinue to use call on your Pokemon until you have no more left and go back to Mt. Battle and just walk back up to him without facing all 9 thugs. Ho-Oh is the hardest. All you have to do is Defeat Mt. Battle all 100 trainers. Then Capture all Shadow Pokemons and purify them and then a message will come up that you will have him but keep a Pokemon slot open so you cann capture him. Raikou can be found as a Shadow Pokemon of Cipher Admin Ean in the Shadow Pokemon Lab. Suicune can be found as a Shadow Pokemon of Cipher Admin Venus in The Under. Tyranitar is the strongest Shadow Pokemon in the game. You only have one attempt at this, so use the Master Ball. The leader of Cipher has it. Also, if missed your chance to get the Shadow Pokemon Tyrannitar and MetaGross, go back to where the Cipher President and his minions are located. You have a chance to fight them all over, and retrieve some of the Shadow Pokemon you did not catch. Metagross and Tyrannitar are some of the most difficult Shadow Pokemon to get.
There is one shadow Pokemon in Phenac City at the beginning. After journeying to Pyrite town, you will find that Cail, a rougue has a shadow Pokemon, and that the trainers in the town square (which is a circle on the pavement with trainers all around it) all have shadow Pokemon. Mirror B. also has a shadow Sudowoodo. The Under has a few trainers with shadow Pokemon, and also, Lady Venus has a shadow Suicune. Dakim of Mount battle has a shadow Entei, and Proffesser Ein of the Shadow Pokemon lab has a shadow Raiku. On Mount battle, many trainers have shadow Pokemon. Realgam Tower also offers many shadow Pokemon and the Deep Under offers 6-10 shadow Pokemon. The after- game area of Snagem Hideout has one of the starter Pokemon that you can catch and then Shadow Lab has the last starter Pokemon.
No you cannot catch Entei in Pokemon Emerald.
