When i insert the game cartridge the words gameboy come up along with nintendo under it but doesnt actually start the game

Hi! First things first, cleaning :)! You could follow this: https://www.retrorgb.com/cleangames.html Do you have more games to test? Perhaps it’s gameboy related instead of the game. If that won’t work at all.. perhaps something inside is broken, anyway you need to open up the game and check the board.

I think what you need to do is resolder the pins on the chips inside of the cartridge. One of them may be loose and by heating it up and getting back the connection should help. I have fixed a Kirby’s Dream Land that was doing the exact thing, so this is probably your issue.
