SplashEdit NG

Standalone scene editor for psxsplash, replacing the Unity-based SplashEdit. Plan and design decisions: psxsplash/splashedit#48.

Download

Nightly build, rebuilt from every push to main: one archive per OS with the editor, the psxsplash engine and pcsx-redux. Per-OS notes are on the release page.

engine/ holds psxsplash.ps-exe, which Play and Run on hardware boot, psxsplash-cdrom.ps-exe for disc images, and builds with on-screen debug overlays: Build > Performance Overlay (FPS counter and heap bar) and Room Debug Overlay (room wireframe) make Play and Run on hardware boot psxsplash-perf, psxsplash-rooms or psxsplash-perf-rooms instead. Disc images always get the plain CD-ROM build. Each also comes as a -nologo build (psxsplash-nologo.ps-exe, psxsplash-cdrom-nologo.ps-exe, ...) without the psxsplash boot logo and jingle: turn off Build > Boot Logo in Test Runs to have Play and Run on hardware boot those, and set Boot logo to off in the scene inspector's Disc section to put psxsplash-cdrom-nologo on the disc. A psxsplash build you point at by hand with no -nologo build beside it boots with the logo, and the build report says so.

Building

Needs CMake 3.24+, a C++20 compiler, SDL3 and FreeType. Dear ImGui and stb are fetched at configure time.

cmake -S . -B build -G Ninja
cmake --build build
./build/splashedit

--screenshot out.png [--size 1600x960] [--mouse x,y] [--clean] [--no-overlays] renders a few frames and writes a PNG (--no-overlays hides the scene view's trigger, interact and nav overlays), which also works headless under xvfb-run. Screenshots skip the startup splash; --splash shows it (silent), --frames N picks the moment.

The UI follows the monitor's scale setting (e.g. 150% on Windows or X11) and rescales when the window moves to another monitor. --ui-scale N (or the SPLASHEDIT_UI_SCALE environment variable; the flag wins) sets it instead, N from 0.5 to 4. Without --size the window opens that much larger, within the screen; --size is always in window coordinates. Scripted --click, --drag, --mouse, --hittest and friends take UI coordinates, so a script works at any scale.

Fonts: Inter (SIL OFL 1.1) and Lucide (ISC), licences in assets/fonts.

Branding

assets/brand holds the psxsplash logo, icon and "made with" badges, copied from psxsplash/brand where tools/build_brand.py generates them. Use these for the window icon, splash/about screens and anything the exporter shows the user; don't draw new logos here. To change the branding, change the generator in psxsplash/brand and copy the output back. The old splat with the PlayStation logo must not be used anywhere.

• icon.svg, icon-*.png: window and app icon
• logo.svg (light backgrounds), logo-dark.svg/logo-dark.png (dark UI), logo-mono.svg (one colour)
• made-with.svg, made-with-square.svg: badges for exported games
• bootscreen.svg: 320x240 reference for the in-engine splash
• boot-jingle.wav, bootlogo-hires.png: the boot logo's jingle and its pieces at 8x the PS1 screen, for the editor's startup splash. bootlogo-hires.png and src/ui/bootlogo_hires.hh come from brand tools/build_bootlogo_hires.py, which cuts the same pieces as the engine's build_bootlogo.py

Colours: #ff3b3b #ffb400 #2ecc40 #1e90ff #b145ff #ff4fa3, ink #16122b.
