An emulator is a piece of software that mimics the operation of a hardware system -- such as an old games console -- through an application on your computer, smartphone or tablet. This can be a processor-intensive operation, and the emulator's game file -- known as a Read-Only Memory file, or ROM -- can noticeably run slowly on your iPhone if it does not have enough free memory available. IPhone emulator apps are only available for jailbroken devices, which have been unlocked from iTunes and can install third-party software from the independent Cydia app store. Install a free settings app to maximize the iPhone's memory and help your emulator run fast.
Things You'll Need
- SBSettings application
Launch Cydia on your jailbroken iPhone by tapping its icon on the home screen.
Tap the "Search" button in the menu across the bottom of the screen and type "SBSettings" in the text box at the top. A list of search results is automatically compiled.
Tap the entry for the SBSettings app, followed by the "Install" button in the upper-right corner. Tap the "Confirm" button on the next screen. SBSettings is installed on your iPhone. Tap the "Reboot" button once installation is complete.
Press the Home button on your iPhone to return to the home screen. Slide your finger across the date bar from right to left to open the SBSettings control panel.
Tap the "Processes" button followed by the small red circle next to each app in the list. Tap the "Delete" button to close each app, followed by the "Free Up Memory" button once all apps have been closed.
Launch your emulator app by tapping its icon on the home screen when the SBSettings control panel disappears. The additional memory space made available by SBSettings will help your emulator and ROMs to run faster.
Tips & Warnings
- Always perform this procedure before running an emulator, and after closing it to ensure your iPhone has sufficient resources for the next app to run properly and at full speed.
- Ensure you do not breach any copyright laws when using an emulator or downloading ROMs to play on it.
