Jellyfin player for the PlayStation 2, styled like the ORBIT launcher (to be published). Jellyfin transcodes to MPEG-2 + MP2 at SD resolution; the PS2 decodes the video on the IPU (libmpeg) and the audio with libmad + audsrv.

wsl bash build.sh          # jfplay.elf (ps2dev v2.0.0)
wsl bash build.sh test     # host selftests; JF_CHECK="http://server:8096 user password" adds the live checks

Copy jfplay.elf and title.cfg to mass0:/APPS/Jellyfin/: the launcher lists it under APPS. It also runs on its own from uLaunchELF.

Settings are read from the launcher's mass0:/orbit/config.ini:

[red]
ip = dhcp

[jellyfin]
servidor = http://<server IP>:8096    ; an IP: the PS2 does not resolve .local names
usuario = <user>
clave = <password>
subtitulos = spa                      ; languages in order (spa, eng); no = off

The log goes to mass0:/jfplay.txt; an answer from the server that does not parse is saved to mass0:/jf_bad.txt.

These files are copies from the ORBIT launcher sources. A fix in one repo has to be copied to the other by hand: gfx.c/h, ui_data.c/h (the launcher's tools/ui_art.py), ini.c/h, net.c/h, iop.c/h, cover.c/h, build.sh.

The fonts have diverged: tools/font.py here bakes all Latin-1 letters plus œ into the ui font (subtitles in French, Portuguese, German...), and gfx.c draws the ASCII base letter when a font lacks one. Regenerate with python3 tools/font.py (needs Pillow).

• docs/phase15-results.md: what was measured in PCSX2 and on the console, and the bugs found.
• tools/pcsx2/: headless PCSX2 harness (Xvfb, virtual USB image, pad input, capture).
• On the console, some full-size Ethernet frames arrive with their last 42 bytes zeroed (ps2sdk netman's D-cache write-back); net.c lowers the MTU to 1400 so the server never sends frames that long.

Developed with Claude Code (Anthropic) as the coding assistant: it wrote and debugged most of the code, drove PCSX2 for testing and read the logs from the real console to track down the hardware-only bugs. Claude Code plugins and tools used along the way:

• OpenSpec: each phase planned as a change with proposal, design, specs and tasks (openspec/)
• Ponytail: a "do the simplest thing that works" mode, to keep the code small
• CodeGraph (MCP server): a code index for finding symbols, callers and impact
