Do gameboy advance emulators not work for iphone anymore?

I have a jailbroke iphone 3gs running on 4.3.3 firmware it was jailbroken with redsn0w. I have read every tutorial i have been able to find and nothing works! I am able to get the cracked version of gpsphone but when i try to get roms it either wont show up on the application or during instalation, it says 404 not found i have used apt123locker but i cant even search for games on there. I dont want to ssh i need to download the roms straightbto my iphone. Please give a simple answer if possible because im no computer wizard. Oh and yes i have the bios. Gpsphone cracked comes with it
