PC Engine/TurboGrafx-16 (TG16) emulator based on Mednafen. Requires iOS 3.1+ and natively supports iPad and iPhone 5 displays. Tested running 60fps on the iPhone 4/4S (3GS or newer recommended). It’s also the very first emulator for iOS to support multiple Wiimotes with full wireless GUI control.
Transfer games to your device using SSH or other file transfer method (The recommended location is any directory under /var/mobile/Documents or /var/mobile/Media). Make sure the “mobile” user has write access to the directory for save functionality. If possible use a program that mounts your device over USB like iExplorer (Windows & OSX), or ifuse (Linux) to speed up transfers
