In plain English

exFAT Image Builder is a Windows desktop application for people who work with PS5 homebrew game images. It gives a graphical interface, so no command line is needed, for building exFAT and ffpkg format game images, automatically backporting games so they run on older PS5 firmware, renaming and organizing game dumps, managing a local game library, sending payloads to a console, and watching kernel logs stream in live. Version 2.5 is described as a major overhaul. All 18 tabs in the app were redesigned, the color theme moved from blue to a purple tinted dark look, and a new three pane inspector was added for the rename feature: a list of games grouped by status on the left, details about the selected game in the middle, and renaming controls on the right. Alongside the redesign, the README lists a long set of bug fixes, covering how cover art is displayed, how duplicate game folders are merged in the library, how folders are recognized as containing a game, and how file renaming handles Windows specific quirks like case only changes. The application needs Windows 10 or 11, administrator privileges, a free tool called OSFMount for building exFAT images, and the .NET 8 runtime if the user wants to build ffpkg images. A valid PS5 game dump containing an eboot.bin file is also required as the source material. The interface supports 17 languages. Building the application from source uses PyInstaller together with Pillow and tkinterdnd2, and the README notes that Python 3.11 is the tested version. The project is released under the MIT license.
