rnc-propack

Mirror of the RNC ProPack compression tool

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.

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 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.

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 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.

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.

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.
