BBR APF Studio is the world's first beginner-friendly modding tool for Beach Buggy Racing (BBR1) — the popular Vector Unit arcade racer. It opens the game's proprietary .apf archive files, extracts every editable database and texture, lets you edit them with a friendly GUI, and repacks the result so you can drop the modded files straight into your game install.
No coding, no command line, no Python setup. Just click, edit, export.
If you've ever wanted to:
- Give your car 999 boost charges per pickup
- Make a rocket-speed turbo that flings your buggy to the moon
- Replace the title-screen logo with your own art
- Rain powerup crates from the sky across entire tracks
- Scale every tree on a track to 4× for a giant jungle effect
- Remove the invisible sky ceiling so cars fly forever
- Edit AI behaviour to create elite opponents
- Repaint car textures, driver skins, HUD icons, menu buttons
…you're in the right place.
- Smart Form mode — every value in every game database renders as a labelled input with plain-English hint tooltips.
- Raw JSON mode — full CodeMirror editor with syntax highlighting, line numbers, bracket matching, code folding, and live multi-error lint underlines for instant syntax feedback.
- Pulsing error bubble jumps you to the first syntax error in one click.
- Opens your APF's texture folder in Windows Explorer.
- Paint / resize / replace 620+ PNGs with any image editor (Paint, GIMP, Photoshop, Krita).
- Delete-and-paste workflow works perfectly — the repacker auto-detects edits via modification time.
- Browse every music track and SFX sample extracted straight from the game's FMOD banks.
- In-app preview player with play/pause, scrubber, buffered-range indicator, volume, and per-row loading spinner.
- Drop any WAV in to replace a sound — Studio matches the original name, re-encodes as PCM16, and patches every FSB5 size field so the game actually plays the new audio.
- Cross-session workspace — close the app mid-edit, reopen, continue exactly where you left off.
- Move, delete, duplicate, or scale any entity on any track.
- Pre-built recipes for giant trees, sky-rain powerups, no-powerup purist mode.
- Works on every stock track: Blizzard Vale, Sandy Shores, Skull Creek, Pyramid Quarry, Lost Tunnels, Volcano Island, and more.
- Python toolkit streams progress via Tauri IPC channels — you see 0 → 100% live during extract and repack.
- Hacker-style decode log for visual flair.
- Ships with an embedded Python 3.12 runtime + Pillow + numpy + texture2ddecoder.
- Works on fresh Windows installs without installing anything else.
- ~23 MB installer, ~80 MB installed footprint.
- Curated "Quick Hacks for BBR1" — 8 hand-picked beginner mods, each with the exact file path and the exact value to change.
- Links straight to my YouTube channel for video walkthroughs.

Installer size: ~23 MB (NSIS-compressed) Installed size: ~80 MB (includes embedded Python + dependencies) Platform: Windows 10 / 11 (x64)
Run BBR APF Studio_1.6.0_x64-setup.exe. Standard Windows installer — Start-menu shortcut + desktop icon.
Open BBR APF Studio. On the Import tab, pick your game's Assets.apf (required) and optionally Expansion.apf. The files live in your Beach Buggy Racing install folder — typically under C:\Program Files\WindowsApps\VectorUnit.BeachBuggyRacing_...\ (Microsoft Store version) or wherever you installed it manually.
Click Extract & Enter Studio →. Progress bar fills live as Python unpacks the archives.
- Edit tab — every JSON database, level, track script, and localisation file appears in the sidebar. Click one to open it. Use Smart Form for guided editing or Raw JSON for direct syntax.
- Textures tab — click Open Textures Folder → Windows Explorer opens → edit PNGs with your image editor → save.
Go to the Repack tab. Pick an output folder. Click 🚀 Repack & Export. Studio rebuilds your modded .apf files with every edit applied.
Copy the files from your chosen output folder into your Beach Buggy Racing install folder, overwriting Assets.apf / Expansion.apf. Always back up the originals first. Launch the game.

| Game | Status |

Honest limits:
- 🚫 3D models (car bodies, track geometry, character meshes) — custom binary format, not decoded.
- 🚫 Animations — custom bone/transform binary.
- 🚫 Collision meshes — custom physics binary.
- 🚫 Audio banks (
.bank) — FMOD Studio proprietary, needs original project. - 🚫 Compiled shaders — HLSL bytecode, GPU-specific.
You can still move, delete, duplicate, or scale references to these assets inside the level JSON files — you just can't reshape the model itself.
I'm someless. I spent many days and nights reverse-engineering Beach Buggy Racing's proprietary APF + VUJB formats — the dual integrity hashes, the quirky body-offset layout, the obscure VUJB type codes, the Windows Store platform marker — so that modders around the world don't have to touch a single line of code.
Every feature in Studio is hand-crafted: the real-time progress pipe, the multi-error JSON linter, the bundled Python runtime, the hacker-style loading overlay, the smart-form hints, the level-scene editor.
BBR APF Studio is 100% free, forever.

Q: Is this legal? A: You own your game copy. Modding single-player game files for personal use is within your rights. Don't redistribute modified game files — distribute only your mod changes (patches, recipes).
Q: Will it work on Steam BBR1? A: The Microsoft Store version is tested. Steam release uses the same engine and should work — untested, report back if you try it.
Q: Can I use this to make a paid mod pack? A: This tool is free — the mods you make with it are your property. You can't resell the tool itself (see LICENSE).
Q: Will my antivirus flag the installer? A: Small unsigned Windows apps often trigger heuristic warnings. The source code is available on request; the binary is built from this repo's release workflow.
Q: Can I contribute? A: Not to the source (closed-core to keep the tool unified). But you can: report bugs, request features via GitHub Issues, or publish your own mod packs showcasing what Studio can do.
Free to download, install, and use for personal and non-commercial modding. Not free to redistribute, modify, reverse-engineer, or resell. See LICENSE for the full terms.
