i recently bought a game boy advance and a copy of Pokémon sapphire, the GBA works well and the Pokémon sapphire cartridge did work on a friend's game boy advance SP.
But when i put the cartridge on my game boy, it only shows the game intro screen, that Nintendo game freak screen and apparently gets freeze, the game's not running.
I clean the dust of the gba bc i saw that is a common issue but nothing happened.
what could be the problem? how can I fix it?
