Summary

Follow up to merged PR #4 on upstream master 6bcc69b01f2fa5af0c0eec83cd2fd8a5ccf79327. Match 23 additional NTSC-U-only level functions smaller than 200 bytes in plain C: 1,792 distinct function-body bytes across 242 level placements.

The latest wave adds three functions (328 body bytes, 18 placements): two multiplayer menu wrappers and a 96-byte table scan present in 16 levels. The table scan keeps the table base separate from its three-word slot offset to reproduce stock compiler output. All 18 placement relocations resolve exactly to retail.

The earlier 36-byte func_L39_005A3D9C starts 4 mod 8 in all 17 multiplayer levels. Its stock compiler output matches retail but has one trailing zero alignment word. After stock MATCH, the build verifies one function, one zero padding word, no other allocated data, and no relocation in the padding. It changes only the generated ELF .text size/alignment metadata. No C instruction or retail byte is rewritten. A standalone PS2 link and every retail placement verify the 36-byte body.

Validation

• Stock native checks report MATCH for all 23 sources with inherited flags, no inline assembly or register pins. Independent relocation proofs cover all 242 retail placements.
• On head fe987850a2a97ca064997e0c5724506602b749a8, the full NTSC-U build reports SCUS_973.53: 54 of 54 targets match. An independent linked-section audit confirms 158 C functions in 2,168 placements and 120,537,627 non-BSS bytes identical to retail across all 54 programs.
• All 50 unit tests pass with python -S; repository checks pass. The staged files were scanned for disc/archive references, private paths, and keys.

Limits

This contribution targets NTSC-U only. The PAL disc is unavailable, so the PAL full build and two-disc carry remain unverified. The official NTSC-U report remains at 6,341 exact functions and 730,328 exact bytes (9.73%) until these linked C functions are carried into that counter. The full build is byte-exact; gameplay has not been validated.

Only C source, build tools, tests, configuration, documentation, and generated header/report updates are included. No retail programs, assembly dumps, game assets, or proprietary toolchains are published.
