How to Mod Your PSP in 2025

Despite being over ten years old, the PlayStation Portable (PSP) is making a surprising comeback in 2025. With its sleek design, extensive game library, and vibrant modding community, the PSP remains one of the most popular handheld consoles. If you’re here, you’ve probably just bought a used PSP or dug out your old one and are now wondering how to unlock its full potential. The answer? Modding.

In this comprehensive guide, we’ll show you how to safely, easily, and legally modify your PSP in 2025 to use custom firmware, play your games from a USB flash drive, emulate retro consoles, and much more.

Why Mod a PSP in 2025?

Modifying a PSP essentially means installing custom firmware (CFW). This opens up entirely new features beyond Sony’s original specifications. With a modified PSP, you can not only back up your UMD games in ISO format and play them directly from the memory stick, but also install emulators, apply responsive themes, utilize cheat engines, and run homebrew apps that improve performance and usability.

Modding is even more relevant in 2025, as physical media becomes increasingly obsolete and digital customization takes center stage. For retro gaming fans, the PSP is a great portable platform for emulating Game Boy Advance, SNES, Sega Genesis, and even PlayStation 1 titles—all in the palm of your hand.

What You’ll Need to Get Started

Before you begin, make sure you’ve got the essentials. Here’s what you need:

• A PSP model (1000, 2000, 3000, or PSP Go are all moddable)

• A Memory Stick Duo (at least 2GB, but 4GB–8GB is better for game storage)

• A USB cable to connect your PSP to a computer

• A computer with internet access (Windows or Mac)

• Some basic comfort with downloading and moving files

Note: Not all memory sticks are created equal. If you’re using a microSD card with an adapter, make sure it’s a reliable brand. A cheap or fake card can cause corruption or data errors during the modding process.

Step 1: Identify Your PSP’s Firmware and Model

The very first step is to find out what firmware version your PSP is currently running.

1. On your PSP, go to Settings > System Settings > System Information.

2. Look at the System Software version. It will be something like 6.60 or 6.61.

3. Take note of your PSP model. This affects how you apply the mod (e.g., PSP-1000 can be permanently modded, PSP-3000 cannot).

If your firmware is older than 6.60, you’ll need to update it first. Most modding tools are designed for either 6.60 or 6.61 firmware versions. These versions are stable and fully compatible with custom firmware tools like PRO-C2.

Step 2: Download the Required Files

Here are the essential files you’ll need to download and install custom firmware:

• Official PSP 6.61 Update (skip this if you’re already on 6.61)
  Download from Sony’s official site

• PRO-C2 Custom Firmware
  This is the heart of the modding process. It gives you the ability to run ISO games, homebrew apps, and more. Look for the latest “PRO-C2” release for 6.60 or 6.61 from a trusted PSP modding site like Wololo.net.

• Fast Recovery Tool (included in the PRO-C2 package)
  This is used to quickly reapply the custom firmware after your PSP powers off, for models that don’t support permanent mods.

Make sure to extract these ZIP/RAR files into folders using software like WinRAR or 7-Zip.

Step 3: Update Your PSP (if needed)

If you’re not already on firmware 6.60 or 6.61:

1. Connect your PSP to your computer using a USB cable.

2. Create a folder inside your memory stick directory: PSP/GAME/UPDATE.

3. Place the EBOOT.PBP file (from the 6.61 update) into the UPDATE folder.

4. Safely disconnect your PSP, go to Game > Memory Stick, and run the update.

Once completed, your PSP will reboot with the new official firmware.

Step 4: Install the Custom Firmware (PRO-C2)

With your PSP now on the correct firmware version, it’s time to install the custom firmware.

1. Connect your PSP to your PC again.

2. Inside the extracted PRO-C2 folder, you’ll find a subfolder called PROUPDATE.

3. Copy the PROUPDATE and FastRecovery folders into the PSP/GAME directory on your memory stick.

4. Disconnect the PSP and navigate to Game > Memory Stick > PROUPDATE on the PSP.

5. Launch the installer. Follow the on-screen instructions, and press X when prompted.

6. Your PSP will reboot — now running PRO-C2 custom firmware.

Optional: Enable Fast Recovery

On PSP-3000 or PSP Go models, the mod isn’t permanent. Each time your PSP shuts down completely, it’ll boot into official firmware. To re-enable the mod:

1. Go to Game > Memory Stick > FastRecovery.

2. Launch it, and your PSP will return to PRO-C2 mode instantly.

You can repeat this step whenever needed.

Step 5: Start Using Your Modded PSP

Congratulations! Your PSP is now modded. You’ve unlocked powerful new functionality and endless fun. Here are some of the cool things you can now do:

Run ISO/CSO Games

You can now backup your physical UMDs into ISO or CSO format and play them directly from your memory stick. Simply create a folder named ISO in the root of your memory stick and drop your game files there.

Install Emulators for Retro Consoles

Some of the best emulators for PSP in 2025 include:

• gpSP – Game Boy Advance emulator

• Snes9xTYL – Super Nintendo

• NesterJ – NES emulator

• PicoDrive – Sega Genesis

Each emulator usually goes into the PSP/GAME folder. You can launch them like any other PSP game.

Apply Custom Themes & Plugins

With CFW installed, you can now:

• Change your PSP’s appearance with custom themes (CXMB plugin)

• Add an FPS counter, in-game music player, or cheat engine (TempAR)

• Tweak performance settings or enable overclocking for smoother gameplay

Is Modding Legal?

Modding your PSP is legal in most countries if you’re doing it for personal use — such as running homebrew apps, emulators, or playing backups of games you already own. However, downloading and sharing copyrighted ROMs or ISOs that you don’t legally own is piracy and not supported by the community.

Troubleshooting Tips

• PSP not reading ISOs? Ensure the files are placed in a folder named ISO on the root of your memory stick.

• Corrupted data error? Re-download the file or try using a better memory stick.

• Freezing issues? Some games need specific settings in the recovery menu or plugins disabled.

At a time when handheld gaming is experiencing a retro revival, the PSP remains a true powerhouse. Modifying it in 2025 is not only easy but also incredibly rewarding. Whether you want to rediscover old favorites, emulate classic consoles, or simply experiment with custom user interfaces, modifying your PSP will unleash its full potential.

Modify responsibly, avoid piracy, and enjoy the endless possibilities of your redesigned handheld.
