A simple and fun 1080p tile-matching puzzle game built for the Blu-ray platform to demonstrate its gaming capabilities.
Co-developed by aefirestone and Gemini as an open-source experimental homebrew project.
- Simple Gameplay: Nothing too fancy, simple match-3 gameplay with a slot-machine theme, match the symbols to score points and chase high scores.
- 1080p Graphics: Nice 2D graphics in full HD
- LPCM audio: Listen to Eric Matyas' background music during gameplay
- Colored Buttons Using your remote, press 🟩 to reveal a hint, and press 🟨 to turn off music anytime.
The Blu-ray (BD-J) platform is not straightforward to develop for. I wrote a tutorial on building a simple Xlet here:
How to code and compile your BD-J
You mainly need to write, compile, and sign the Java code (other disc files can usually stay as-is).
Important: BD-J uses Java 1.3, not modern Java.
| Platform / Player | Memory / Heap Profile | Status | Notes |
|---|---|---|---|
| CyberLink PowerDVD | 2 / 2 MB RAM | 32 MB Max Heap |
✅ Perfect | Runs perfectly with full rendering, audio, and menu navigation. |
| PS4 | 6 / 16 MB RAM | 23 MB Max Heap |
🟡 Needs Polish | Game runs but missing slot symbol graphics (SLOTS.png). |
| Philips BDP1502/F7A | 1-2 / 2 MB RAM | 16 MB Max Heap |
🟡 Needs Polish | Severe input lag when navigating with the remote control. |
| Sony BDP-S6700 | 1-2 / 2 MB RAM | 16 MB Max Heap |
🟡 Needs Polish | Severe input lag when navigating with the remote control. |
| Sony BDP-S390 | Hardware Specs N/A | ❌ Known Issue | Black screen with audio |
| Seikou¹ | Hardware Specs N/A | ❌ Known Issue | Black screen with audio |
| VLC¹ | Hardware Specs N/A | ❌ Known Issue | Cannot launch game due to being stuck in a broken/cropped menu screen / missing "background.jpg" |
*All of these players' firmware has been up to date. ¹VLC and Seikou are community made Blu-ray emulators that uses libbluray, may not be 100% accurate with BD specs
- Black Screen (BDP-S390/Seikou): Some players experience a blank screen while audio continues to stream, pointing to a graphics plane compositing mismatch.
- Audio Playlist Fallback: Could not make multi-track audio playlists to work
00000–00004, strict standalone hardware players occasionally default to stream00000if secondary.mplsindex tables aren't explicitly verified by the authoring tool. - Memory Garbage Collection: Extended play sessions on lower-spec hardware may require tighter tracking of temporary image buffers during cascade matches.
- Optimization: The game was intended to play on the weakest Blu-ray player new and old, and be BD compliant. Optimizing the game to the lowest common denominator will help make the game run in most players.
Contributions, bug fixes, and hardware test reports are more than welcome! Whether you're an experienced embedded Java developer, a homebrew enthusiast, or someone with a stack of physical Blu-ray players to test on, feel free to open a Pull Request or Issue.
