== Disc Archaeology ==
''Findings from a byte-level analysis of the Japanese demo disc image (194,600,960 bytes / 94,720 blocks; 255 filesystem entries).''
=== A command-line demo player ===
The disc's program is <code>/Demo</code> (51,648 bytes), a movie/demo player whose Unix-style usage text survives intact — typo included:
<code>demo [FilaName] -f [fps] -v [volume] (-m -b)</code> — with options documented as ''"-f...Set fps option (default is 24)"'', ''"-v...Set Output volume (default is 0x4000)"'', and <code>-m</code>/<code>-b</code> selecting whether the parent is the main or battle task.
The player's error strings are a typo collection: ''"FilaName"'', ''"Cab't open InitEventUtility"'', ''"Can;t search Drawing buffer pointer"'', ''"DIasplayScreen faild error"''.
=== A disc with no LaunchMe ===
The startup script (<code>AppStartup</code>) ends by declaring ''"the system will start $boot/Launchme"'' — but '''no LaunchMe exists on the disc'''. The only executable is <code>/Demo</code>, which expects command-line arguments. This is consistent with the disc being driven by an external menu or store-kiosk system rather than booting standalone, fitting its Panasonic (hardware-maker) publisher.
=== Development leftovers ===
* The BGM directory preserves the project's raw audio pipeline: numbered <code>.4416</code>-format sample files (<code>TAKI02</code>–<code>TAKI25</code>) and loosely-named stage streams, among them the misspelled <code>jupitarstage</code> and <code>olgol</code> (オルゴール — "music box").
* <code>/data/SE/SE1/</code> holds 19 loose, unpacked <code>USE*.AIFC</code> sound-effect samples — working files that later builds ship only inside packed archives.
* Win/lose card art exists for only two fighters (<code>card_moon</code>, <code>card_jupiter</code>), suggesting the demo's versus mode was scoped to a Moon-vs-Jupiter showcase.
=== Filesystem notes ===
The redundant directory copies ("avatars") of <code>/System/Drivers</code>, <code>Folios</code>, <code>Programs</code> and <code>Scripts</code>, plus <code>rom_tags</code>, disagree between copies — stale older generations from multi-pass mastering. The root directory copies verify hash-identical, so this is a mastering artifact, not dump damage.
=== Unallocated space ===
20,222 blocks (~40 MB, 21% of the disc) belong to no file, in three runs. Every byte was checked: 100% standard <code>iamaduck</code> mastering filler, nothing hidden inside.
=== Demo vs Retail ===
The Panasonic-published demo disc is not a trimmed copy of the Bandai retail game — it was cut from an '''earlier snapshot of the project''', before several asset-pipeline overhauls:
* '''Character animation naming''': the demo ships <code>moon0.pak</code>/<code>moon1.pak</code> per fighter; the retail disc uses the later <code>moon1P_0.pak</code>/<code>moon2P_1.pak</code> per-player scheme. The demo roster is five fighters (Moon, Mars, Jupiter, Venus, Uranus) against retail's full lineup.
* '''Music pipeline''': the demo's BGM is raw numbered <code>.4416</code> sample files (<code>TAKI02</code>–<code>TAKI25</code>) plus loose stage streams — including the misspelled <code>jupitarstage</code> and <code>olgol</code> (オルゴール, "music box") — where retail reorganized everything into per-character AIFF banks. The demo's sound-effects tree still contains a folder of loose unpacked samples (<code>SE1/USE*.AIFC</code>) that retail ships only in packed archives.
* '''Missing systems''': the demo has no <code>FONT</code> data (no staff-roll/profile text system) and no <code>gmdebug</code> debug program; its interface archives (<code>SubData</code>) are five files against retail's ten, and the shared ones differ in size — different builds, not copies.
* '''Identical media''': the big Cinepak movies (<code>Opening</code>, <code>Moon.FILM</code>, <code>moon08.film</code>, <code>moon16.film</code>) and <code>MidiData.pak</code> are byte-for-byte the same sizes on both discs — the video and MIDI content was locked before the demo was cut.
