Delta Emulator: SEGA Genesis Core – Steps to install Delta iPac to play SEGA Genesis / Mega Drive games on iPhone without jailbreak

Wanted to play SEGA Genesis / Mega Drive games on Delta, but couldn’t wait for Riley Testut’s Delta? Then use Delta iPac.

Delta iPac is not official build from Riley Testut but rather a fork done by Delta fan – ianclawson a.k.a iPac (hence the name) – that comes with many additional features – one of them is the ability to play SEGA Genesis / Mega Drive games. I have tested to install and play it myself, so far the experience is good and nothing difference from the official Delta build from Riley.

Delta iPac is forked from Delta with SEGA Genesis Core, Multiplayer support and AirPlay to TV and Monitor. How awesome is that?

Just to give you the idea, here are the differences between Delta (official build from Riley) and Delta iPac.

FeaturesDelta (Official, non-Beta)Delta iPac
NES (Nintendo Entertainment System)YesYes
SNES (Super Nintendo Entertainment System)YesYes
N64 (Nintendo 64)YesYes
GB (Game Boy)YesYes
GBC (Game Boy Color)YesYes
GBA (Game Boy Advance)YesYes
NDS (Nintendo DS)YesYes
Sega Genesis / Mega DriveNoYes
AirPlay for dual screen to TV / MonitorNoYes
Multiplayer supportsNoYes

The official Delta non-Beta build doesn’t have SEGA Genesis / Mega Drive games support yet, as the SEGA Genesis / Mega Drive core is still currently in beta – at the time this article is written – and only accessible to Riley’s Patreon supporter. I would encourage you to help support him especially if you think Delta is a great app. So in case if you are looking for the official Delta build, you can refer to this article instead: Official Delta Emulator: Step by step guide to install & Play Retro console games on iPhone without Jailbreak (NES, SNES, N64, GB, GBC, GBA, NDS) at JILAXZONE. However, if you are ok with the fork made by iPac, then stay reading as I’ll walk you through on how you can install this emulator.

Step 1) to Step 6) Read here.

For details of step 1) to step 6) – including all download links, I have detailed and provided them here on this link: Complete guide how to sideload apps/games into iPhone/iPad without jailbreak at JILAXZONE. You need about 15-30 minutes, depends on your internet connection to complete everything – since mostly are either downloading software or registering account.

Once you have done all the first 6 steps, then continue on subsequent steps below.

Step 7) Get latest Delta iPac app.

Step 7a) Open the following link on your iPhone using Safari browser. Find “Delta-iPac.ipa” and tap on it to start download the IPA file.

Download link

Step 7b) Once downloaded, open Files app, then navigate to the Safari downloaded folder (typically under “On My iPhone > Downloads”), you should see a file with name Delta-iPac.ipa.

In case you can’t find the “Delta-iPac.ipa” file inside Files app, then you need to first configure your Safari download folder to a folder of your choice (but I do recommend to set it here: “On My iPhone > Downloads”), check it out here: Configuring Safari Download Folder on your iPhone at JILAXZONE and re-download the “Delta-iPac.ipa” file.

Step 8) Install Delta iPac to iPhone.


Before proceeding to the steps below, ensure you have done Step 1) until Step 7) and ensure you have AltServer running on your Computer and your iPhone plugged in to the same Computer that AltServer is running.

With iPhone connected to your computer with AltServer running, follow these steps:

Step 8a) Run AltStore app. On your iPhone, tap AltStore app icon to run it.

Step 8b) Navigate to My Apps. Once AltStore is opened, tap on “My Apps” tab.

Tap “+” to install Delta iPac

Step 8c) Tap on “+” button located on the top left of AltStore screen.

Step 8d) Navigate to the Safari downloaded folder where you have downloaded Delta-iPac.ipa file. Tap on the file to begin installing. In case prompted, key-in your Apple ID and password – this is required for code signing.

Delta-iPac.ipa should now in-progress being installed to your iPhone, you just need to wait until it finished installing. Once finished installing, it will appear on “My Apps” tab under “Active” section.

Just to be sure, you can go back to your iPhone Home screen and check whether you can see “Delta (iPac)” app icon (White triangle with purple background) on the Home screen. If you can see “Delta (iPac)” app on your Home screen, that means you have successfully installed Delta iPac on your iPhone.

Congrats! At this point, you can safely remove your iPhone from your computer.

Step 9) Run Delta iPac on iPhone.

Running Delta iPac on iPhone is as simple as tapping the “Delta (iPac)” app icon. If this is your first time opening Delta iPac, you won’t see any retro games (SEGA Genesis or other Nintendo games) on it. You need to get your own games for it. See the next step.

Step 10) Transfer retro games into Delta iPac.

Delta iPac – at the time this article is written – is able to play the following retro console games: SEGA Genesis / Mega Drive, NES, SNES, N64, GB, GBC, GBA and NDS. Due to legal reasons, I won’t detailed here on how you can get your hands on the games but Google is your best friend to find out how you can extract your own retro console games.

However, I would like to remind you this:

Please DO RESPECT the Console Maker, Game makers, Developers, Publishers by always buying and playing the originals on their original systems. Without you supporting them, there won’t be any good and great systems and games in the coming future.

Once you get your hands on retro games you want to play, you can use these 2 methods to transfer your retro games into Delta iPac.

Method 1) Import games without computer

One of the method of transferring retro games into iPhone is via iTunes (On screen, copying DreamCast games into iPhone via iTunes).

Method 2) Import games with computer

You can check both method in detail using this guide here: How to import games into Delta Emulator running on your iPhone & iPad at JILAXZONE.

Do note, however, when transferring the games into your iPhone, choose “Delta (iPac)” folder rather than “Delta” folder.

Step 11) Start the game.

This is the moment you have been waiting for! Once you have transferred your SEGA Genesis / Mega Drive or other retro compatible game(s) into Delta iPac, just tap the game from the list to start the game. The game should start running and playing on your iPhone screen. Enjoy!

Controller Recommendation

Playing retro games is always better with controller!

While you can always use the touchscreen of the iPhone to play the games, but for greater fun and enjoyment, I would recommend you to play the games with the Controller using physical buttons – so the experience is (almost) the same like the original. Just in case you need recommendation, here they are. I am personally using Nimbus and DualShock 4 to play the games.
