Disc Archaeology

Findings from a byte-level analysis of the European retail disc image (425,287,680 bytes / 207,360 blocks).

A hidden fifth language — including a rejected take

The M4 release advertises four languages, shipping its two text-bearing scenes in each (A035E/F/G/I.DAT, A099E/F/G/I.DAT) with flag-graphic selectors (FLAGE, FLAGF, FLAGG, FLAGI). But the disc carries more:

• FLAGJ.3DO — a Japanese flag graphic among the selectors.
• A035j.dat — a full 28,299,532-byte Japanese-language version of scene 35.
• A035jbad.dat — a second, different 28 MB encode of the same Japanese scene, literally named "bad" — a rejected take pressed onto every European disc beside its replacement.

There is no Japanese A099, so the fifth language is incomplete — a vestige of an abandoned five-language plan, shipped with 56 MB of Japanese video (half of it explicitly marked as a reject) that the release never uses.

Why the disc is twice the size of the NTSC releases

The European image is ~205 MB larger than the US pressing, and the accounting is exact: localization was done by brute force. Rather than overlaying translated text on shared video, the two text-bearing scenes were re-encoded wholesale per language — scene 35 exists six times (four languages plus the two Japanese takes, ~28 MB each, +141 MB) and scene 99 four times (~12.8 MB each, +38 MB), with the remaining ~33 MB being extra filler on a larger disc layout. The language variants are also fresh encodes, not copies — their sizes differ from the US originals of the same scenes.

A 308 KB symbol file at the disc root

/play.sym is a full Macintosh debug-symbol file for the player — 11,358 type, structure and function entries, opening with the source object :Objects:main.c.o — the complete source-level map of the engine, shipped on retail.

Structure notes

The 26 shared scenes use lowercase .dat names while the language-variant scenes are uppercase .DAT — two generations of the asset pipeline visible in the case convention. A flagback.3do backdrop serves the language menu. The score digits keep their ONE/TWO/TRE/FOR/FIV/SIX names.

No text credits

No staff names, "ReadySoft" or "Elite" exist as text anywhere on the disc — all credits are inside the video.

Filesystem notes

The root directory copies verify hash-identical. The copies of /System/Drivers, Folios, Programs, Scripts and rom_tags disagree between generations — the common multi-pass mastering artifact; not dump damage.

Unallocated space

21,244 blocks (~42 MB) belong to no file. Every byte was checked: 100% standard iamaduck mastering filler.

Regional Comparison

The 1993 US, 1993 Japanese and 1994 European (Elite, M4) releases share the same core: 29 scene files (A004–A099, their gappy numbering inherited from the arcade original's scene list) that are byte-for-byte the same sizes across all three regions — the laserdisc footage was converted once and never touched again. What changed:

• Japan (1993): a near-identical twin of the US release — the same file set, with the executable rebuilt 4 bytes smaller (its internal source file renamed from 3doplay.c to 3do.c). A full-image sweep finds no Japanese text anywhere: the Japanese release shipped entirely in English, on a slightly larger pressing with more filler.
• Europe (1994, M4): the real localization. The two text-bearing scenes ship in four languages each (A035E/F/G/I.DAT, A099E/F/G/I.DAT — English, French, German, Italian, ~28 MB and ~12 MB per language), selected via flag graphics (FLAGE–FLAGI.3DO). The disc also carries a vestigial fifth language: a Japanese flag (FLAGJ.3DO) and a Japanese scene 35 — twice (see the EU page's Disc Archaeology).
• The score-digit overlays are charmingly named ONE, TWO, TRE, FOR, FIV, SIX in every region.
• No region contains any text credits — no ReadySoft, Bluth or staff names exist as strings on any disc.
