The console is an extremely complex piece of hardware, with many very powerful components, even for today. You need a high end device to achieve good performance.
We recommend at least a Snapdragon 845-equivalent device. This means 4 large cores (Cortex-A75 level). If you only have two big cores (e.g. Snapdragon 700 series SoCs, you should not enable multi-threaded VU, and performance will suffer as a result). Devices with Mali or PowerVR GPUs will run the app, but performance will be lower than Adreno GPUs.
If you want to use the app on a slower device, you can try it, but games will run slow, especially heavier titles. You can try underclocking the CPU by setting the cycle rate to a negative number, and the cycle skip to a positive number in System settings, but this will cause games to lag internally at best, or crash at worst.
Expectations.
This is a free app, worked on as a hobby in the developer’s free time. At the time of writing, it is in very early stages and missing many useful features, however is usable for playing some games.
It is not going to be perfect, far from it. I will continue to improve it when I have time, but please remember this is not my job, and to have realistic expectations, especially if you do not have a high end device.
As it is an early preview, you should save your game regularly in case of crashes.
The app tells me I need a BIOS.
Yes, you do. A BIOS image is required to play games and is not optional. This image should be dumped from your own console, using a homebrew application. There are plenty of guides available online on how to dump your console’s BIOS.
My games are running slow/lagging.
Different games have very different hardware requirements, due to how much they utilized the various components of the console. You can try underclocking the CPU by setting the cycle rate to a negative number, and the cycle skip to a positive number in System settings, but this will cause games to lag internally at best, or crash at worst.
How to improve performance?
Make sure fastmem is enabled in System settings.
Enable Multi-Threaded VU1 in System settings. This will cause lower performance if your device does not have at least three "big" CPU cores.
Use the Vulkan renderer if you have an Adreno GPU. Note that some games will perform better with OpenGL, and may not render correctly with Vulkan. Mali GPUs are not tested with the Vulkan renderer.
Underclock the emulated CPU by setting the cycle rate to a negative number, and cycle skip to a positive number in System settings.
For some games, enabling the Preload Textures and GPU Palette conversion options in Graphics settings can improve performance.
If the game slows down depending on the camera angle, this may be due to GS downloads, which are very slow on mobile GPUs. You can try disabling hardware readbacks in Graphics options, but this may create some glitches in effects.
How do I customize the touchscreen controller (position/scale)?
Press the pause or back button while ingame, and tap the controls tab in the top-right corner. You can also add additional buttons for hotkeys here, e.g. fast forward, quick load/save, etc.
The app opens in portrait mode, how do I change it to landscape?
Turn your device around if you have auto rotation enabled. You can also force it to always use landscape in the first page of App Settings.
My Bluetooth controller isn’t working.
Map the controller in "Controller Settings". You can start with the automatic mapping, but sometimes triggers or sticks still need to be mapped manually.
I want to set different settings for each game.
Long press the game in the game list/grid, tap Game Properties, and tap the Game Settings tab. If you want to change these settings while in-game, open the pause menu, and tap the info button in the top-right corner to access Game Properties.
My games have rendering glitches.
Due to the complexity of the console’s hardware, there are still plenty of issues which arise when using the hardware renderer. You can try using the software renderer for these games.
I want to save more than one state.
Open the pause menu and tap Load/Save state, there are 10 slots + a quick save (for onscreen buttons).
I want copy my saves from another device.
Currently you can only import an entire memory card at once; it is not possible to import individual saves. Swiping from the left in the game list will show an "Import Memory Card" option which you can use to import a *.ps2 image of a memory card.
Where are my saves located?
Due to scoped storage on Android 11+, we cannot place your saves in a normal directory on external storage. However, with a file explorer app, you should be able to access the Android/data/xyz.aethersx2.android directory, in your primary storage volume, which contains your save states and memory cards. Note that accessing this directory requires granting additional permissions to your file manager on Android 11+.
How do I add covers to the game grid?
Place cover images in the covers directory, located in the data directory mentioned above, with the file name as the game title or serial in jpg/png format. Alternatively, you can long press in the game list and select "Choose Cover Image" to import an image.
How do I create launcher shortcuts for games?
Long press the game in the game list, and select "Create Launcher Shortcut".
