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)

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)

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:

  • 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…

Road map

Help or Ideas welcome

• Pick patches from other forks
• GLES, Vulkan, VR Rendering
• Publish to other distros (appimage, snap)
• Modernize asset format (JSON, GLTF?)
• Interpret behavior scripts (Lua, JS?)
• Parse other engines' tables
• Revive pinedit (Qt4) ?
• Mentor me to join Debian developers

Try code

• CVS migrated to GIT on sf and mirrored:
  • https://github.com/rzr/pinball
• 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:
  • https://sourceforge.net/projects/pinball/
• Ping me on FediVerse:
  • https://purl.org/rzr/pinball
