I doubt it is the Game Shark's fault. Do you have the National Dex from Professor Oak yet? You would get it after beating the E4 and having 60 Pokemon in your Pokedex. You cannot obtain pokemon that aren't members of the original 150 until you recieve the National Dex. I played for 2 days where my Golbat tried frequantly to evolve into Crobat but couldn't because I didn't have the National Dex. Once you obtain it your pokemon should evolve as usual when they level up again.
As pointed out here it's likely because you don't have the National Dex so Trapinch's evolved forms and even Trapinch itself are not recognized. Look through your Pokedex Trapinch should NOT have an entry if you don't have the National Dex since it's a pokemon outside Kanto, or else it's there with a blank entry and '???' as it's dex number and stats (I'm not sure because I've not experimented with this).
To receive the National Dex from Oak you need to defeat the Eilte Four and Gary and have seen at least 60 Pokemon. It's a sh**** system since a lot of Kanto pokemon have evolved forms outside the Kanto dex but there it is.
Gameshark is a risk though because it's forcing the game to process data it's not designed to and so use
will at times come with bad karma.
I too once had FR/LG on emulator and used gamesharking to capture a few pokemon I couldn't obtain in the wild, though I believe only one was outside Kanto (a Phanpy I think). While battling Misty I accidentally forgot to turn the gameshark off and somehow my Pikachu which was legitimately caught in the Viridian Forest turned into a bad egg. That then forced me to gameshark a new Pikachu since you can't return to the Viridian Forest once in Cerulean City until you defeat Misty, gain the ability to cut and reach Vermillion. Until you can fly Digglet Cave in Vermillion City is the only way to return to Pewter. I couldn't wait that long, I needed that Pikachu to battle Misty.
So even if this problem wasn't caused by gameshark you need to be careful doing that but if you really want Trapinch's evolved forms you'll need to gameshark them or else gameshark yourself the National Dex if that's possible.
