running another emulator inside PPSSPP

[xy1331]

Thanks for the list of PSP emulators, but I've already downloaded the ones I want to use (Atari800 & Castaway).

My question is whether anyone's successfully used one of the Atari 8-bit or 16-bit emulators from within PPSSPP on their iPad (or other iDevice).

For some reason there are no Atari 8 or 16-bit emulators for iOS, jailbroken or not.

Thank you.
