GEPS is a Graphics Editing Program for SNES homebrew development. GEPS can create, load, edit, and save tilesets and palettes that can be used on SNES hardware. GEPS supports multiple tileset formats (serial, planar, and intertwined) and a varying number of bits per pixel (1, 2, 3, 4, and 8). Tilesets can be viewed and edited using different subpalettes (depending on the number of bits per pixel being used).
For the full changelog for GEPS, see CHANGELOG.md.
You can download the latest release version of GEPS by looking at the latest package and downloading the already-built executable .jar file.
GEPS can also be built using Maven. You can download and install Maven if you don't already have it. Once Maven is installed, you can use the following commands:
- Use
mvn testto run unit tests. - Use
mvn packageto compile a package in the current repository. This should produce a runnable JAR file. - Use
mvn cleanto clean the target folder, removing files produced by any previous build. - Use
mvn clean packageto clean and then rebuild the package. This will compile a package from scratch.
In order to run, GEPS requires Java SE 14 or later. If you already have Java installed, you should be able to check which version you are using by entering java -version into your terminal / command line. You can get the latest version of Java SE from OpenJDK or Oracle JDK.
