Pokemon Stadium 1 and 2 control issue (PLZ HELP)

[leftsidejuggalo]

so i downloaded a couple different versions of Pokemon stadium 1 and 2 just cuz it sounded fun. but i came across a problem that irritates me. all of the controls work except the arrow buttons. they dont work at all and therefore i cant navigate through the menus. is there a problem with my emulator or is it the games themselves? i play other game with no problems, such as Mario 64, Legend of Zelda: OoT, perfect Dark, and Yoshi Story. The arrow buttons work no problem with those games, but will not work for Pokemon Stadiums 1 and 2. Do I need a controller maybe? Please help me if possible.
