celPix
celPix finds, views and edits the graphics inside retro-game ROMs and dumps. It reads a wide range of pixel and palette formats, decompresses the common console compression schemes, and writes edited pixels and palettes back to the original file.
- A wide variety of pixel and palette formats
- Compression with a decompressed preview and in-place editing
- Tilemaps, spritemaps and fontmaps that render a ROM's own maps, sprites and text
- Drawing tools with undo/redo and copy/paste to external image editors
- Indexed and RGB PNG import and export
- Slices, bookmarks and projects that save a session to pick up later
- Plugins for custom formats, from config files to full Python code
Compatibility: Uses the C library of the system (may need glibc 2.35 or later)

Usage
celPix is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. Awesome!
AppImages are single-file applications that run on most Linux distributions. Download an application, make it executable, and run! No need to install. No system libraries or system preferences are altered. Most AppImages run on recent versions of Arch Linux, CentOS, Debian, Fedora, openSUSE, Red Hat, Ubuntu, and other common desktop distributions.
This AppImage uses the C library of the system and may need glibc 2.35 or later. It does not run on distributions that use a different C library (such as musl on Alpine Linux) or an older glibc.
Running celPix on Linux without installation
Unlike other applications, AppImages do not need to be installed before they can be used. However, they need to be marked as executable before they can be run. This is a Linux security feature.Beware! AppImages are usually not verified by others. Follow these instructions only if you trust the developer of the software. Use at your own risk!
Download the celPix AppImage and make it executable using your file manager or by entering the following commands in a terminal:
chmod +x ./*.AppImageThen double-click the AppImage in the file manager to open it.
Sandboxing celPix
If you want to restrict what celPix can do on your system, you can run the AppImage in a sandbox like Firejail. This is entirely optional and currently needs to be configured by the user.
Updating celPix
If you would like to update to a new version, simply download the new celPix AppImage.
The celPix AppImage also can be updated using AppImageUpdate. Using this tool, celPix can be updated by downloading only the portions of the AppImage that have actually changed since the last version.
Integrating AppImages into the system
If you would like to have the executable bit set automatically, and would like to see celPix and other AppImages integrated into the system (menus, icons, file type associations, etc.), then you may want to check the optional appimaged daemon.
Note for application authors
Thanks for distributing celPix in the AppImage format for all common Linux distributions. Great! Here are some ideas on how to make it even better.
Pro Tips for further enhancing the celPix AppImage
Please consider making the celPix AppImage self-contained, so that it does not depend on the C library of the system and runs on more distributions: ship the C library including its loader (ld-linux-*.so.*) and use it to launch the application, or link statically.
Thanks for shipping AppStream metainfo inside your AppImage. Please open a pull request on https://github.com/AppImage/appimage.github.io/blob/master/data/celPix if you have changed it and would like to see this page updated accordingly.
