Well i had a amazing discovery with my pokemon yellow i bought a couple of years back. As some of आप may know, there are like two known ways to get missingno. Who ever told आप that is wrong! I found over seven other ways to get missingno! On चोटी, शीर्ष 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...
आप start out in Cerulean City. आप must not have beat the gym there and must not have battled the guy अगला to the nugget bridge that says,"I saw your feat from the grass!"and of course आप must go and defeat the nugget bridge people. With all that said, lets get to how the cheat works! आप go up route 24 and as soon as आप get to the end of the nugget bridge head left. Go down until आप are one step away from being directly अगला to the water that takes आप to the Unknown Dungeon. As soon as आप walk that one step press START right when आप press the down button. The guy standing there will see आप but instead of engaging in battle the START menu will come up. Then आप will have to teleport (using an ABRA आप 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 आप beat him, the buttons will be able to work again. Head north and right when आप reach route 24, the START menu will pop up. When आप close the menu, आप will go into a battle (without being in the grass! WOW!) and the pokemon आप will battle is a MEW! Now here is the hardest part. Catching this pokemon is not easy. It is treated like a legendary so आप have to either put it to sleep या paralyze it and knock out most of it's HP. As soon as आप do that, आप will have yourself a MEW!
