Reverse-engineering notes on Microcosm (Psygnosis, 1994) for the Amiga CD32: 92% of the data track is one 483 MB video file of 30,707 frames, decoded straight into 8 AGA bitplanes. Documentation only.

Reverse-engineering notes on Legends (Krisalis Software, 1996) for the Amiga CD32: a six-floppy A1200 game on a CD, a Bytekiller decruncher, a hand-written LoadSeg, and the developers' photographs

Reverse-engineering notes on HeroQuest II: Legacy of Sorasil (Gremlin, 1994) for the Amiga CD32 — RNC ProPack 1 with a rotating XOR key, a hunk file that decrunches and relocates itself in 584 bytes, and an ECS display on AGA silicon with Akiko measured to zero.

Reverse-engineering notes on Gloom (Black Magic Software / Guildhall, 1995) for the Amiga CD32: a chunky texture-mapped renderer that never touches Akiko, because its framebuffer is a copper list with one MOVE per pixel

Alfred Chicken (Twilight / Mindscape, Amiga CD32, 1993): structural documentation read from an original pressed disc, the first physical one in this set. Settles that the thirteen-zero CATALOG is the mastering not the dumper, that the overrun past the declared volume is cut into the glass master, and verifies MODE1/2048 by descrambling.

Reverse-engineering notes on Marvin's Marvellous Adventure (21st Century Entertainment, 1994/1995) for the Amiga CD32: disc layout, Puzzle V2.0 level format, planar graphics, in-house music modules, CDXL intro, and a great deal of leftover development material.

Reverse-engineering notes on Guardian (Acid Software, 1994) for the Amiga CD32: a polygon engine that fills every scanline with one Blitter cookie-cut into four interleaved bitplanes, a 24-bit per-scanline copper sky, and Akiko measured to zero for the eleventh time

Structural teardown of Myth: History in the Making (Amiga CD32, System 3). The disc is the 1992 three-floppy release pressed whole - three 880 KiB disk images plus an 18 KB shim - behind a hole of exactly 50 MiB. Bytekiller under the magic DAVE, a hand-written LoadSeg, an Akiko CD driver, and a PVD date the disc itself falsifies.

Reverse-engineering notes on Dragonstone (Core Design, 1995) for the Amiga CD32: disc layout, RNC ProPack, the AmigaDOS boot chain, three-language text, and the leftovers -- a cut level, a floppy prompt, and an Exec object file in sector 21.

Reverse-engineering notes on Prey: An Alien Encounter (Almathera / KirkMoreno Multimedia, 1993) for the Amiga CD32 — an hour of speech streamed as 1,225 identical 60 KB files, no audio track, and the disc that says where the Commodore trademark block's exec fragment came from

The canonical Amiga CD32 / CDTV platform checklist, carried from one documentation pipeline to the next: disc identification, the trademark block at sector 21, the AmigaDOS epoch, RNC ProPack, hunk executables, copper lists and planar bitmaps.

Structural documentation of the Amiga CD32 release of Universe (Core Design, 1994): a 16-opcode bytecode interpreter, RNC ProPack nested three levels deep, 602 KB of four-language script, Akiko's CD-ROM and I2C EEPROM ports driven by hand, and an ECS display on AGA silicon.

James Pond 2: Codename RoboCod (Amiga CD32, 1993) — measurements of the pressed disc: a 128.000000 MiB hole, 93.9 % of the file bytes as CDXL video, a three-language manual with no characters in it, and a boot script that is a signed development diary. Nineteenth disc in the CD32 set.

Index of the Amiga CD32 / CDTV disc documentation: one repository per pressing, each with the full per-disc write-up, plus a link to the shared platform checklist they all feed into. Format archaeology only - no disc images, no game assets.

Liberation: Captive II (Byte Engineers/Mindscape, 1994, Amiga CD32) — the largest CD32 data track in the series, 91 % of it speech: three Wyvern shared libraries that are the 3D engine, 10,792 pre-rendered wall sprites instead of a texture mapper, three generators run at boot, and a text system that shipped with its author's note to translators

Reverse-engineering notes on Banshee (Core Design, 1994) for the Amiga CD32: a same-label control against Dragonstone, a 640x512 HAM8 picture nothing runs, RNC ProPack method 2 inside an executable, and a debug hook in the shipped boot script

Structural documentation of the Amiga CD32 release of Fire & Ice: The Daring Adventures of Cool Coyote (Graftgold / Renegade, 1994) - ISO 9660 layout, PowerPacker 2.0 containers, copper-driven AGA display, cd.device use, and the leftovers of its floppy ancestry. Documentation only, with Python tools that reproduce every figure.

Structural documentation of The Speris Legacy (Amiga CD32, 1996, Binary Emotions / Team 17): the Imploder decruncher taken out of the game, the LEV2 level format rendered, the copy-protection code tables reconstructed, and a CD32 disc carrying the CDTV .TM block.

Structural documentation of Gunship 2000 (MicroProse, 1994) on Amiga CD32: a 100 MiB zero hole, an unreachable Pirates! Gold demo, little-endian IFF, and 542 validated RNC2 streams. Documentation only.
