Well i had a amazing discovery with my pokemon yellow i bought a couple of years back. As some of anda may know, there are like two known ways to get missingno. Who ever told anda that is wrong! I found over seven other ways to get missingno! On bahagian, atas of that the MEW glitch in yellow is actually legit! It does exsist! I did it twice and got two mew's! I tried doing these glitches and all of them work!

So, this is one way to get MEW...
anda start out in Cerulean City. anda must not have beat the gym there and must not have battled the guy seterusnya to the nugget bridge that says,"I saw your feat from the grass!"and of course anda must go and defeat the nugget bridge people. With all that said, lets get to how the cheat works! anda go up route 24 and as soon as anda get to the end of the nugget bridge head left. Go down until anda are one step away from being directly seterusnya to the water that takes anda to the Unknown Dungeon. As soon as anda walk that one step press START right when anda press the down button. The guy standing there will see anda but instead of engaging in battle the START menu will come up. Then anda will have to teleport (using an ABRA anda can catch from the route connecting Cerulean and Saffron City.) Use ABRA to warp back to Cerulean. (you must have healed at the pokemon center there first.) The START and "A" button will not work. Go and battle the swimmer at the gym and after anda beat him, the buttons will be able to work again. Head north and right when anda reach route 24, the START menu will pop up. When anda close the menu, anda will go into a battle (without being in the grass! WOW!) and the pokemon anda will battle is a MEW! Now here is the hardest part. Catching this pokemon is not easy. It is treated like a legendary so anda have to either put it to sleep atau paralyze it and knock out most of it's HP. As soon as anda do that, anda will have yourself a MEW!
