The most effective method for playing PlayStation 2 games on an Android smartphone is AetherSX2
For a very, very long time, PlayStation 2 emulation on Android has been in an odd place. Although it has been feasible to imitate the system on your smartphone using a specific emulator that is accessible on the Play Store, many people, including us, refused to promote the software even though it was the greatest method to play them. The greatest method to play PlayStation 2 games on your Android smartphone right now is with AetherSX2. The Google Play Store is where you can get it for free, and it's also the fastest.
The results of my experiments to determine which games work and don't work are shockingly outstanding. Right now, you still need a smartphone with the highest standards in order to utilize AetherSX2. Depending on which game ran the best, I experimented on the OnePlus 9 Pro running Android 12 by switching between Vulkan and OpenGL. Even though the OnePlus 9 Pro is one of the most potent emulator smartphones available right now, it fails to run some of the most well-known games at 100% speed. I tried out The Simpsons: Hit & Run, Need for Speed: Underground 2, and the original Ratchet & Clank. Sonic Heroes was another game I wanted to test since the most recent build had broken what had previously worked flawlessly.
This is an early alpha build, please be aware. We've been testing a private alpha build that the developer provided us access to for a few weeks. A public alpha is currently available, and you may join up for it. There are presently a lot of broken games and features, and upgrades might bring about regressions. For further details, you could also visit the official AetherSX2 website.
The greatest app for playing PlayStation 2 games on a phone is AetherSX2.
Only Play!, a high-level emulator that doesn't require a BIOS to function, and PCSX2, which is in breach of the licensing agreement, are available as alternatives for PlayStation 2 emulation. Although AetherSX2 uses PCSX2 code, the PCSX2 creators have been kind in their support of AetherSX2. The licensing problem has also been discussed by the PCSX2 developers; in essence, the core code is LGPLv3 licensed, and any remaining GPL-covered code in AetherSX2 will be eliminated by the time the software is formally published. AetherSX2 is currently accessible in early alpha.
A 64-bit device with "big"/performance cores is required to run AetherSX2, and the developer suggests at least a Snapdragon 845. Depending on whatever runs better on your device, you can play games using Vulkan or OpenGL, and you may switch between the two while you're playing. AetherSX2 has several fantastic features, such as internal resolution scaling, save states, various control schemes, and more. It's still in alpha, as was already said, thus performance may vary depending on your computer. For instance, Ratchet: Gladiator (also known as Ratchet: Deadlocked in the U.S.) was just recently made playable since, prior to a recent update, it would crash after finishing the opening cinematic.
Tahlreth said on Reddit that the LGPL sections would be made accessible upon request for anyone asking for the source code. Additionally, "to relink the combined shared library as needed by the license with the given object file," as stated in the license. Tahlreth claims that no Java source code will ever be made available to the general public, citing the need to avoid clones that are loaded with pop-up ads and in-app sales. This argument does make sense given that there are already apps out there claiming to be AetherSX2. Both ads and internet access are absent from AetherSX2. The distinction between the LGPL and the GPL is that the LGPL permits developers to use portions of the code in their own projects, provided that those portions are relicensed under the LGPL. The remainder of the project may operate under a different license. The entire project would have to be GPL-licensed in the event of GPL.
There is just one control stick and no D-Pad, which you may have observed if you've watched any AetherSX2 footage as well. By visiting the emulator menu, this may be modified while a game is still in progress to show those additional controls. The issue is that, given the smaller screen real estate, there isn't much of a purpose to display things constantly, especially given how many games can be played without them. Ratchet: Gladiator was the only game I had issues with since you need the second control stick to turn the camera.
Aether SX2 configuration for optimum performance
You may take actions to enhance AetherSX2's performance, and the creator has actually tested it extensively on their POCO F3 with the Snapdragon 870. There are a ton of settings you may experiment with, but I've only changed three of them.
The GPU renderer is the first parameter you may change and is perhaps the most important. The performance you receive will depend on the device you're using and the game you're playing, and you may select between Vulkan or OpenGL.
Consider the Vulkan Graphics API, developed by the Khronos Group, as an alternative to graphics APIs like OpenGL or OpenGL ES. It is supported by organizations like NVIDIA and Intel, and its goal is to provide creators with additional choices when creating cross-platform games. Additionally, it has less CPU overhead, which might result in enhanced performance. As Tahlreth points out, OpenGL's framebuffer fetch feature makes it just slightly quicker in some games. The result will depend on you.
Underclocking is the next choice, and I've found that 75% underclocking produces excellent results. The third and last one is "skip showing redundant frames," a new option that was included in the most current AetherSX2 version at the time of writing. It makes an effort to determine the internal framerate of the game and stops it from displaying duplicate frames. Games like Need for Speed: Underground 2 went from being nearly unplayable to operating at a constant 100% speed thanks to a combination of this and underclocking.
Tested games include Ratchet & Clank.
I was most eager to play Ratchet & Clank on my smartphone because it was one of my favorite PlayStation 2 games growing up. Although performance isn't yet flawless, there are measures you can take to make it better. No adjustments or other changes were made to the AetherSX2 experience while recording the aforementioned video using the OnePlus 9 Pro.
Necessity: Underground 2
One of the games that needed further adjustments to function properly was Need for Speed: Underground 2. But when a 75% underclock was applied and duplicate frame rendering was disabled, the performance increased from about 50% to 100%. The game did hang at the very end of the video, which was also recorded on the OnePlus 9 Pro. It is a remarkable accomplishment that this game runs as well as it does here considering how difficult it was to mimic it on PCSX2 for years.

Simpsons: Hit and Run
I frequently return to The Simpsons: Hit & Run while testing cellphones since it is a game I am quite acquainted with. This is unquestionably the greatest way to play the game with AetherSX2, and it runs far faster than it does through programs like Dolphin Emulator. Even though there were several graphical bugs on the Google Pixel 6 Pro, the game performed well – better than on Dolphin Emulator. Below is a little video clip of some gaming. GPUs other than Adreno GPUs cannot use the Vulkan renderer.
ways to download AetherSX2
AetherSX2 is now in a public alpha stage, so it's simple to try it out even though it isn't completely free on the Google Play Store. Simply enroll in the alpha while connected into your Google account, or go to the app's listing in the Google Play Store and do so from there.
AetherSX2 is a huge improvement over the PlayStation 2 emulators that have come before it. We're eager to watch how the emulator develops and advances in the future thanks in large part to the help of the PCSX2 developers. I'm eager to see how the brand-new Qualcomm Snapdragon 8 Gen 1 performs. Try it out and let us know what you think in the comments, please!
