Emilia Pinball's Life
- 2000: Henrik Enqvist wrote game:
- Plain C++ + OpenGL + SDL-1.2
- Plus editor (Qt4) for creating new tables
- http://pinball.sf.net
- 2003: I contributed patches (ports, 3ds) table
- then owned maintenance of project
- 2002: Landed in Debian main (thx)
- 2019: Orphaned (don't panic: I'll adopt it)
- 2020: new tables in debian/testing
Community contribs
- Held extra tables contributions:
- Legal reasons: licenses mix
- Scalability: assets size (.ogg, .xcf)
- Advised to separate assets from engine
- Autofools blocked tables creators
- Community split into forks
- I isolated and maintain separate packages

Legacy to Modern ?
- Desktop OpenGL app on current SW stacks ?
- Mesa3D, X11 => Wayland, KMS…
- API: OpenGL 1.x, GL4ES => GLES, Vulkan ?
- Need BSP, Port: Yocto/OpenEmbedded
- Benchmarked SBCs (STM32MP1, db410c, Pi)
- ARM GPUs with FLOSS (Etnaviv, freedreno)
- using custom profiler "trako"
- Need a "stable" reference system: Debian
OE/Yocto Demo (WIP)
Pinball + Cabinet = Pincab
Low cost DiY
- Bill of Material: ~ BTC 0 (Reuse, Salvage)
- Digital signage: Philips BDH4251V_00 (XGA)
- 2 trestles: ~40kg leveled to ~95cm
- A 2004 PC (x86 Pentium 4 duo 32bits)
- Buttons (Keyboard or mice + strip)
- Validated gear using FuturePinball 2010
- Closed source Abandonware (DirectX8)
- Install on Linux using lutris (wine)
- I <3 Freedom : Libre Emilia (Native Linux app)
Pincab on Emilia
- Support "portrait" display
- New camera "full" static view
- Scripts to boot to random table
- X11, Wayland, systemd
- Read Only FS
- New inputs (& outputs ?)
- Button controls using mouse events:
- Flippers: Right|Left, Plunger: Middle
- Nudges: (R|L)&M , (R&L)&M
Demo Pincab
Sensor input
- "Nudges Control" is not intuitive
- Rely on motion sensor is more natural
- Used NXP FRDM-K64F board (Thx NuttX/NXP)
- MCU ships Accelerometer (FXOS8700Q)
- Made a PoC on MBed OS using HID classes
- Contributed driver to NuttX
- Could be ported to other HW or RTOS:
- Zephyr, RIOT, FreeRTOS, TizenRT…
Demo: Nudge sensor
Road map
| Task | State |
|---|---|
| Emilia "pincab profile" scripts | Implemented |
| Release "final" SDL-1 version | WIP |
| Port to OpenEmbedded/Bitbake | Implemented |
| Release new SDL-2 version | Implemented |
| Publish debian, OE (meta-games) | Planned |
| Deploy to Single boards | WIP |
Help or Ideas welcome
Try code
- CVS migrated to GIT on sf and mirrored:
- Debian is project reference OS:
- Build "snapshot" deb package from scripts
- Use docker recipes from any OS:
- Windows needs WSL + X11 server
- Issues, patches are welcome:
- Ping me on FediVerse:
Create or improve?
