DS emulator for iPhone (cydia)?

I saw my friend last year playing on his jailbroken iPhone a game that was made for DS(I think it was black, or one of the recent ones, like fire gold).So I know there are emulators out there, or ways of playing it. Can someone help me out?

Added (1). I already jailbroke my iphone a long time ago…

I can't really help you out with the ds part but to get cydia is easy just go to blackra1n.com and follow the instructions for getting the jailbreak on your iphone. Then you can explore the add ons and stuff once cydias on your phone. Hope it helped

  • Transfer Pokémon from a GBA Emulator to a NDS Emulator on my iPhone? I have a GBA (Gameboy Advance) Emulator on my iPhone and I would like to get the NDS (Nintendo DS) Emulator, but I don't know how to transfer my Pokémon between the rom files. I have spent a lot of time leveling up my Pokémon from Firered, Leafgreen, and Emerald, and I don't want to lose them all! Does anyone know how to transfer them between the Roms?
