What is PPUX?

PPUX is a Lua-based NES graphics editor built with LÖVE2D that lets you edit CHR-ROM tiles, sprites, palettes, and nametables in a game-aware context. Drop an NES ROM to auto-load tailored layouts from its database (covering titles like Contra Japan or Kirby's Adventure), or build custom windows for static art, animations, and PPU frame renders—unlike basic editors that force manual screen rebuilding. Export edited ROMs and Lua project files without overwriting originals, with PNG drag-drop imports for quick sprite or tile workflows.

Why is it gaining traction?

It stands out with ROM-backed views like OAM animations and nametable unscrambling via Konami-style codecs, plus palette linking that syncs colors across windows for authentic NES rendering. Developers dig the undo/redo, pixel-perfect editing modes (tile vs. edit), and high-speed painting toggle for low-latency drags. The in-app database and Lua projects make iterating on specific games faster than generic tools.

Who should use this?

NES ROM hackers tweaking Contra levels or sprite sheets, pixel artists prototyping 8x8/8x16 assets for homebrew games, and retro modders needing PPU-accurate previews without emulators. Ideal for those tired of hex editors for graphics dumps.

Verdict

Try PPUX if NES pixel editing is your jam—solid docs, E2E/unit tests, and build scripts for cross-platform apps make it usable despite 19 stars and 1.0% credibility score. Still beta (v0.0.8), so expect rough edges in advanced ROM features.
