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.

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 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 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

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.

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.
