How do I evolve Pokemon without any way to trade or any kind of gameshark..

Certein Pokemon will ONLY evolve when TRADED, or get them by CHEATING. No other explanations.

Umm, well, most Pokemon evolve by reaching a certain levels. Most evolve by the use of a stone. Some cannot evolve without being traded, you must either find a way to trade those Pokemon, or cheat to obtain them in their evolved form.

If you're talking about Pokemon like Haunter, Kadabra, Onix, etc., then you must trade or cheat; there's no other way. With every other Pokemon, it's kind of obvious and I'm assuming that you already know.

You can't dude, you need to trade in order to evolve some pokemon.

Fight each and evry trainer who comes in your way. Try and fight every wild pokemon.

There are some Pokemon who can be eveolved when traded only.

Here's what I did: Get yourself a second used GBA, (doesn't need to be a GBAsp, the old model will serve the purpose), they're so cheap at GameStops, etc., and a link cable ($2-$5), and as long as you have more than one game that's compatible (Ruby, Sapphire almost immediately & FireRed, LeafGreen after you fix the machine for Celio and become the Emerald Champ. ), you can trade with yourself! It's a great way to get all the starters, and all traded Pokemon get extra experience, so trade away! Only certain Pokemon need to be traded to evolve, and some need hold items, too. Check a Pokedex for the details on who needs what to evolve, or if they just level up or don't evolve at all. I'm older than most so I really didn't know anyone to trade with and that was my solution. I hope this helps!

If they arent evolving then use a stone

Try stuffing the Pokemon with it's item in the gts and withdraw it or if you have two games you could self trade
