- slot A 29/29 (md_MAIN_013..041 @ 0x800CAE08), slot B 6/6 (md_MAIN_042..047 @ 0x800CCB1C), boot trio 3/3 (md_MAIN_001 [=MAIN/0 twin], md_MAIN_008, md_MAIN_011 @ 0x800CEDF8) — every one BYTE-IDENTICAL on its FIRST build (byte-corroborating the §S44 loader table for slots A/B/boot) - TLO roster derived from the §154 id-word law (.run/s45/derive_tlo.py): 0x4 default; 011=0x7C, 025=0xC, 034=0x80, 039=0xC (first-prologue scan) - new_binary.sh: module hdr carve is now a dot-typed .rodata PAIRED with the c segment — a header can hold a function's jump table (md_MAIN_034), and standalone rodata emits .L locals that don't cross objects; bin links in the data block (both refuted by bytes) - A4 law: symbols.resident.txt dropped from the boot trio's stacks (windows inside the resident region; DsMix @0x800D1BD8 had minted a phantom fn boundary in md_MAIN_011) — re-extracted clean, all three byte-identical, phantom gone

# splat config TEMPLATE — Brave Fencer Musashi location overlays (SCxx.CD/FILE_nnn/0.4.dec)
|
|
# =============================================================================
|
|
# Phase 13: the reusable flat-blob splat config for a LOCATION OVERLAY. ~134 overlays
|
|
# all stream into the SAME RAM slot (vram 0x80128158) and chain into the resident engine
|
|
# (0x800CEDF8) + the EXE. This is a TEMPLATE: the @TOKEN@ placeholders are substituted to
|
|
# produce config/splat.<alias>.yaml — by tools/new_overlay.sh (Phase 13 T4), or by hand
|
|
# (Phase 13 T1a for the first overlay). It is NOT a valid splat config until instantiated.
|
|
#
|
|
# Placeholders:
|
|
# md_MAIN_042 binary alias, ov_<SCxx>_<nnn> e.g. ov_SC01_077
|
|
# extracted/retail/MAIN.CD.dir/FILE_042.dir/0.1 extracted 0.4.dec payload path e.g. extracted/retail/SC01.CD.dir/FILE_077.dir/0.4.dec
|
|
# d17d43e59a4c5bc879936110ca4cdf152f6827c9 sha1 of the 0.4.dec (the build-identity target; also -> config/check.<alias>.sha)
|
|
# 0x800CCB1C load vram (the shared overlay slot) e.g. 0x80128158 (constant across overlays today;
|
|
# parameterized so a future non-0x80128158 overlay needs no template edit)
|
|
# 0x278 file offset where code ends -> data tail begins (iterated vs the byte check, T1b)
|
|
# 0x27C file size in bytes (the EOF marker; = the 0.4.dec length)
|
|
#
|
|
# Modeled on config/splat.resident.yaml (the Phase-10 flat-blob recipe), with overlays'
|
|
# differences: (1) code at file offset 0x0 (overlays open with a function prologue, NOT a
|
|
# leading data word like the resident — so NO leading-rodata trick by default; see the
|
|
# commented `head` slot for the rare pre-code-data overlay); (2) symbol_addrs_path ALSO
|
|
# stacks config/symbols.resident.txt because overlays reference resident engine globals;
|
|
# (3) vram is the overlay slot. Everything else matches the resident options verbatim.
|
|
#
|
|
# Byte-match is robust to the exact text/data split (splat round-trips the bytes — the
|
|
# resident precedent); iterate 0x278 against `make check BINARY=md_MAIN_042` (Phase-5/10
|
|
# precedent). LZSS is NOT in the verify path — we match the DECOMPRESSED 0.4.dec (repack is Gen3).
