You might have seen a lot of talk about PS2 Emulation coming to iPhone of late, and if you've had a niggling voice in the back of your head saying that things might not be as they seem, then you'd be right.
iPSX2 is a fully AI-assisted port that supports JIT for better performance, and while it's widely being spread as being ported from PCXS2, it's not 100% accurate. According to gaming afficionado Mr. Sujano, iPSX2 is based on ARMSX2, which itself is an unofficial fork of PCSX2. It's also closed-source, which violates the GNU General Public License that stipulates that any amended code taken from open-source projects must remain open-source.
Essentially, there should be an easy and public way to download the code for free, just like the developer who “stole/copied” (we'll let you decide) the Xbox emulator that was recently made available for iOS users.
A couple of things about iPSX2:
— Mr. Sujano | All Stuff, No Fluff (@MrSujano) March 24, 2026
- It's based on ARMSX2, which is an unofficial fork of PCSX2
- It's vibe coded
- It's closed source, violating GPL licensing
- It has to be sideloaded
- it does support JIT (benefit of sideload vs app store)
Official ARMSX2 for iOS is on the way https://t.co/eLsYnaKufh
Another thing that you might not have realised is that it's coded by AI, otherwise known as vibe coded. The whole thing has to be side-loaded, meaning you can't just download it off the App Store like Delta and PPSSPP, and all in all, it's more trouble than it's worth. It's because of Apple's current stance on JIT (Just-in-Time) emulation and the problems with programs spitting out code in real time that they can't monitor and put through their stringent checks.
So, currently, to get iPSX2 on your phone, you'll need to trick it into thinking you're an Apple Developer, side-load it on, and mess around with a load of settings in order to make it work. And because of the whole Apple Dev workaround, you'll need a PC or Mac for the initial stages. And you'll need the newest iPhone too if you want the best performance, which means shelling out extra money that we all don't have right now.
Mr. Sujano goes on to explain that there will be an official iOS app for ARMSX2 heading our way soon. My advice would be to wait until there's something more concrete that comes out that you can play using your phone, or get a handheld emulator (which we've thoroughly tested many of to let you know which are the best for PS2 gaming) that you can rely on.
PS2 emulation might be arriving on iPhone, but it's not quite there yet. Hold on a little longer.
