The era of the PlayStation 1 console gave the world thousands of cult games that many players would like to replay or experience for the first time on modern mobile devices. The emulator ePSXe has long been considered the gold standard for running projects of this era on PC, and its appearance on the Android platform was a real gift for retro gamers. However, unlike simple arcade games, launching full-fledged emulation requires proper configuration of the BIOS, plugins and controls.
The installation and configuration process may seem complicated to a beginner due to the abundance of technical terms and the need to search for system files. However, after spending 10-15 minutes on the initial setup, you'll have access to a huge library of classics right in your pocket. In this article, we will analyze each stage in detail: from searching for the necessary files to fine-tuning graphics and sound for maximum comfort.
It is worth noting right away that the legality of using the emulator in itself does not raise questions, but loading games (ROM) and the system BIOS should only be done from your own disks. We do not provide links to copyrighted content, but we will explain how to prepare your device to work with the system image.
Preparing the file system and searching the BIOS
The first and most critical step is to have the file BIOS. The emulator will not work without this system image, as it emulates the original console hardware. The file usually has the extension .bin and weighs about 512 KB. You need to copy this file to the internal memory of your smartphone.
The standard folder structure for ePSXe involves creating a directory bios at the root of the internal storage or in the application folder. If you are using a file manager, make sure the path looks something like this: /sdcard/bios/. Without the correct placement of the file, the application will simply display an error upon launch or offer to download it from an unofficial source, which we do not recommend doing.
⚠️ Attention: The BIOS version must match the region of the games you plan to run. For European games (PAL) you need a European BIOS, for American games (NTSC-U) - an American one. Incompatibility will result in a black screen or freezing.
It is also worth preparing a folder for the games themselves in advance. Create a directory roms or gameswhere you will put disk images in the formats .iso, .bin/.cue or .pbp. A clear organization of files will help the emulator quickly scan the library and display game covers.
Use the .pbp format (PSP eBoot) for games consisting of several disks - this allows you to switch disks directly in the emulator menu without going to the file system.
Installation and initial configuration of the emulator
After preparing the files, you can proceed to installing the application itself. Find the installation package APK from a reliable source or use the official application store if the version is available there. When you first launch ePSXe automatically scan the folder bios.
If a file is found, you will be prompted to select it from the list. After selecting the BIOS, the main menu will open. Here it is important to immediately go to the settings section to optimize the operation for the characteristics of your processor. Go to Preferences and make sure that the correct video driver plugin is selected.
For most modern smartphones with Snapdragon or MediaTek processors, the best choice is the built-in plugin PeopsxPSX or GPU Driver, using OpenGL ES hardware acceleration. This ensures a smooth picture even in heavy scenes.
Setting up controls and connecting a gamepad
Touch controls on a smartphone are often inconvenient for dynamic games, therefore ePSXe offers a flexible system for customizing on-screen buttons and support for external controllers. You can change the transparency, size and location of the buttons on the screen by going to Input Preferences.
To connect a physical gamepad (for example, from an Xbox, PlayStation or universal Bluetooth controller), pair in the Android settings. Then in the emulator, select the input mode Gamepad. Usually the device is detected automatically, but sometimes manual button binding is required.
- 🎮 Press the setup button in the corner of the screen to enter calibration mode.
- 🔘 Sequentially press the buttons on the physical gamepad to assign them the D-pad and action functions.
- ⚙️ Save the control profile under a unique name for each game if the requirements vary.
Pay special attention to setting up the analog sticks. In games like Tony Hawk's Pro Skater or Ape Escape tilt accuracy is critical. In the input settings menu, you can adjust the dead zone of the stick to prevent character drift when there is no touch.

Optimizing graphics and performance
The picture quality in the emulator can be significantly improved compared to the original console. In the video settings section (Video Preferences), options for anti-aliasing, texture filtering and increasing internal resolution are available. However, enabling all effects at once can lead to a drop in FPS on weak devices.
It is recommended to start with basic settings: enable Bilinear Filtering for pixel smoothing and set the rendering resolution 2x or 3x to the original one. This will ensure sharp images on high-resolution screens without putting significant strain on the GPU.
If you are experiencing texture flickering or artifacts in certain games, try changing the frame emulation mode. Switching between modes Normal and Alternate in the GPU plugin settings often solves problems with displaying translucent objects.
| Settings | Recommended value | Impact on performance |
|---|---|---|
| Resolution | Native or 2x | Medium (depending on GPU) |
| Filtering | Bilinear | Low |
| Smoothing (AA) | Off or 2x MSAA | High |
| Frame skipping | Auto or 0 | Low |
The secret of high performance
Disabling controller vibration emulation (Rumble) can save up to 5% of processor resources, which is noticeable on older smartphones.
Working with saves and states
One of the main advantages of emulation is the ability to use Save States (save states). Unlike regular saves within the game, which are only possible at special points, states can be created at any time.
To quickly save, use a combination of buttons (usually Select + R1 or a custom button in the menu). State files are stored in a separate folder and allow you to instantly return to the moment before a difficult jump or boss.
You should not rely solely on states. Be sure to use the standard game save system through the "Memory Card" menu, as state files may become damaged when updating the emulator or changing the Android version. Keep backup copies of important progress.
⚠️ Attention: Save States are not compatible between different versions of the emulator or when changing the game region. Do not try to load the state from the NTSC version into the PAL version.
Solving common problems and errors
Sometimes users experience that the game starts, but the sound lags behind the video or is completely absent. Most often, the problem lies in the settings of the sound plugin (SPU). Try switching the sound emulation method from Interpolation to Simple or changing the sampling rate.
If the game crashes immediately after the splash screen, check the integrity of the image file. Damaged .iso files are a common cause of failures. Also make sure that for multi-disc games you have configured the file correctly .cueif you are using the format .bin/.cue.
In cases where the emulator runs slowly on a powerful device, check if the power saving mode is enabled in the Android system. It can limit the processor frequency, which is detrimental to emulation. Add ePSXe to battery optimization exceptions.
Most problems with sound and graphics are solved by switching plugins in the Video and Audio settings, and not by reinstalling the application itself.
Frequently asked questions (FAQ)
Where to legally download the BIOS for PlayStation 1?
The only legal way to get the BIOS is to extract it from your own PlayStation 1 console using a special cable and dump software. The emulator does not come with this file due to Sony copyright.
Why are games running slow on my new smartphone?
Check the power saving settings. Also try disabling anti-aliasing and lowering the rendering resolution. Sometimes the problem is the processor overheating, which causes the system to reset frequencies.
Is it possible to play online multiplayer via ePSXe?
No, ePSXe Android does not support online multiplayer over the Internet. It emulates a local console. Network play requires other solutions or emulators with netplay support, which is rare for mobile versions of PS1.
How to switch disks in games on multiple media?
Use the emulator menu (usually the "Menu" button on the screen), select "Change Disc" and specify the path to the file of the next disk. In the .pbp format, this is done automatically through the game menu.
Does the emulator support cheat codes?
Yes, there is a section in the settings for entering cheat codes. GameShark and CodeBreaker formats are supported. Codes must be entered manually or imported from a file compatible with the version of your game.
