Memory card instability or a fake/counterfeit storage medium.
If you play your PSP games via the popular emulator on a PC, smartphone, or modern handheld gaming Android device, you do not need ISO Tool 1.31. Modern emulators read unpatched .iso files flawlessly and handle modern compressed formats like .chd much more efficiently. Summary of Pros and Cons Advantages Disadvantages Operates entirely on the console without a PC Text-heavy, outdated user interface Fast UMD disc copying capabilities Higher compression levels can cause in-game lag Excellent compression features for tight storage Mostly obsolete if using modern emulators
For PSP (PlayStation Portable) enthusiasts during the late 2000s and early 2010s, keeping up with the latest game releases was a constant challenge. Sony continually updated the PSP’s firmware with new security measures, designed to prevent the latest games from running on custom firmware (CFW). Enter —a game-changing homebrew application that allowed users to decrypt, patch, and convert game ISOs directly on the device. This article provides a complete guide to ISO Tool 1.31, covering everything from its core features to installation steps, usage instructions, and troubleshooting tips.

If you have limited space on your Memory Stick Pro Duo, CSO (Compressed ISO) format is a lifesaver. ISO Tool 131 includes a fast converter to switch between the two formats, allowing you to reduce the size of your game files significantly. 3. Decrypting EBOOT.BIN
Beyond decryption, ISO Tool became the go-to application for applying various game-specific patches, converting ISOs to the compressed CSO format to save memory stick space, and even ripping a user's own UMD discs to ISO files. It streamlined a process that once required a PC and multiple complex steps into a few button presses on the PSP itself.
First, download the latest version of ISO Tool (e.g., v1.981). The download is typically a compressed archive (e.g., a .7z or .rar file). Inside, you'll find a folder named something like iso_tool . This folder contains the application's data and the EBOOT.PBP file.
Unlike PC-based software (such as UMDGen or PowerISO), ISO Tool runs directly on your PSP. This means you do not need to constantly tether your console to a computer to alter game data, bypass firmware requirements, or patch anti-piracy features embedded in later-generation PSP titles.
