Yes I did just that adding it to the configs folder then the game started instead of crashing to the desktop.
Thanks again for the help maybe eventually I can get a controller working on it to actually enjoy the emulator :D.
Iām glad I was able to help you all

Did you have to code sign the cores even jailbroken? Iām JB on 9.0.2 and I can get the front end to load with but the cores arenāt showing up after moving them to the folder.

Mi amigo, yo te ayudo. Tienes que correr el emulador en Cached interpreter, no funciona el Dynamic Recompiler. Si necesitas mƔs apoyo, dime.
como hago esoā¦
To JuanJo: If youāre on STOCK iOS 9 and are using RetroArch9 which is compiled from the latest github then you actually need to codesign the cores and then transfer them to the ācoresā folder for them to work. There is no way to load the cores that are inside RetroArch.app within RetroArch9 (those cores are signed upon installing to your springboard). However, the other RA9 ipa is an older version from June which allows you to load a core from within RetroArch.app (these cores are inside a folder āModulesā and are signed upon installing to your springboard with whatever signing service that you use: like Zeusmos or iPAWiND). However, if you were jailbroken then itās a lot easier to load up the cores. But letās just say that you got the cores workingā¦ For the mupen64plus core to work it must be set to āCached_interpreterā. The Config file for mupen64plus is included inside the RAR. All you have to do is transfer it to the āConfigsā folder if youāre using RetroArch9. If youāre using RA9 then you put it in the ā.RetroArchā folder.
Para empezar, como dice el compaƱero de abajo, tienes tu dispositivo con jailbreak?
si, esta con jailbreak podrias traducirme un poco de lo que dice porfa?
Entonces como tienes el jailbreak aver intenta esto. No sĆ© si funcione pero intĆ©ntalo. Con ifile busca la aplicaciĆ³n de RetroArch donde este instalada y copea los cores que vienen instalado adentro del folder āModulesā. Copealos al folder ācoresā. Aver si funciona. Tiene que funcionar por quĆ© tienes el jailbreak.
[QUOTE=Quadzilla;29584]I did finally get it working with cached interpreter and then it will not detect my new controller lol.
Retroarch from everything i can find supports MFI controllers so im not sure why it wont work with my Gamevice controller.
I cannot seem to catch a break today.[/QUOTE]
Yeah. It totally sucks. I canāt get any MFi controller working eitherā¦ Iām on 1.2.2
Let me know if you figure anything out.
ya lo copie con el ifunbox y nada 
que hago, se me cierra en el emu de n64, con el de snes me va normal, pero en el de n64ā¦ nada
psdata: tengo un mando ipega 9017, con ese juego en el SNES9X, le hara al retroarch?
no habia leido lo anterior, ya pase el archivo a la carpeta config, ahora solo me faltaria usar el mando ipega
el emu de n64 ya me funciona

Glad to see you have the same issue or rather glad to know I am not alone in this issue.
Everyone else seems happy on here lol so I have no clue what they are using .
I gave up because I have no idea where or how to fix such an problem.
A JuanJo:
Me da gusto que lla te funciona. QuƩ bien. 
im not sure if this nightbuild has mfi support, by now i need BTstack, so at least i can use my ps3 controller.
