A recompilation of the Tales of Legendia game on the PS2

What is this project?

Requirements

How to use it

Do not publish data, out or tools\\.build. They may contain user inputs, extracted game files or generated derivatives.

Status as of Session 51 (2026-10-30). If PS2_PROJECT_STATE.md has a higher session number, this table is stale.

Milestone	Status	Note
Boot chain — SIF/RPC, IOP modules, all six MBS archives mount	✅ Working	Syscalls and stubs implemented; no I/O stall
First rendered frame ("NOW LOADING")	✅ Verified	Confirmed from a framebuffer dump, not just a counter
ADXF asset streaming	⚠️ Flaky	~10% of runs still deadlock in ADXF_GetPtStat; residual cause unknown
Scene rendering after the load transition	❌ Blocked	Geometry is submitted but degenerate at the GIF level (zero-height sprites) → black screen
Build speed	⚠️ Slow	Tree is an MSVC Debug build; clang-cl + Ninja + Release is far faster
Overall	🚧 In progress	Evidence, history and next steps: PS2_PROJECT_STATE.md

Documents

01 — Overview	the disc in one screen, the six answers
02 — The disc and the volume	single layer from the volume, 37 files, sector accounting
03 — Containers	AFS, the MBS tables, the CPS envelope, CRI's return
04 — The executables	the ELF, the compiler stamp, the I/O processor side
05 — The block codec on this disc	the census, the engine, and the two things missing from it
06 — Decoder lineage	the headline: the measurement and its controls
07 — Media and the disc budget	video, ADX, AHX, MIDI, and where 4.08 GB went
08 — CDVD.000	the gigabyte that is not padding
09 — Leftovers	the archaeology, in full
99 — Open questions	twelve, each with its measurement

Reports

Committed output of every tool run: reports/ — volume descriptors and file listing, the sector map, the AFS census and the full CPS decode census, the ring-site scan across all eighteen executables, the decoder disassembly, the prefix scans with all four controls, the reference decoder's negative test with its positive control, the whole-image signature sweep, the CDVD.000 profile and census, the disc budget, the media census, and the executable's string sweep.

Tools

Python 3, standard library only, one file per job: tools/ — see tools/README.md.

tales_block.py is copied from tales-blockcodec-doc without a single edit — md5 e2dcd6b8dc717b84f67bf8a46568298c, identical to the corpus copy and to Tales of Rebirth's. It is committed here even though it finds nothing on this disc, because the test it fails is a result and a test only counts if the instrument is the same one that succeeded elsewhere. iso9660.py, ps2elf.py, dismips.py, prefix_scan.py and sector_map.py are copied from ps2-talesofrebirth-doc unchanged; ring_sites.py gained one flag, --imm, and its default is still the corpus's 4078/4079.
