You can't (**Cry**)
You can't play Pokemon Platinum on visual boy advance. It's a Nintendo DS game and visual boy advance can only play gameboy games.
To play Pokemon games on computer you have to download a emulator I would recommend these: Desmume No$gba (not for gba games) and for playing gba games: Visual Boy Advance
vba is only 4 gba games
You could get a Rom for one of the Pokemon mystery dungeon games and then use visual boy advance to play it.
You can't. Pokemon Pearl is a NDS game, and VBA (visual boy advance) can only play Gameboy Advance games. For Pokemon Pearl, you have to look for NosGBA or another NDS Emulator.
Go to emulatorzone.com then the Vba (Visual Boy Advance) will start to download. After you have downloaded that go to doperoms..com to download a Pokemon game like ruby sapphire emerald yellow, any GBA games and Gbc games, but not Ds or dsi games
well first get an emulator I reccommend Visual boy advance all you have to do for that is type it in on Google the first link will have it its very safe and reliable you down load it then go to www.doperoms .com and type in Pokemon crystal on there search bar it will come up then press download ROM they have all Pokemon games Visual boy advance will also play game boy color and game boy advance games including all the Pokemon games

You can play Pokemon for Gameboy, Gameboy Colour and Gameboy Advance on your PC by downloading Visual Boy (just google *visual boy*). ---- Then google *pokemon game roms* to find how download it. - MeritBadgeHelp
try a search in dgemu.com for Pokemon games. You'll find a ton of roms you can play.
ezroms.com, coolroms.com
There are many sites you can visit. I myself prefer www.rom-gods.net for mine. They not only have all the regular Pokemon games, but many hacks as well. Enjoy!
