Power Drive (Denton Designs for US Gold) on the Amiga CD32 — one MODE1/2352 track of 38,133 sectors, 68.39 % of them zero, holding 161 files: a 1992 rally game in 135 RNC ProPack files that close 135 of 135, six cars in 583 headerless frames of 240 × 150 × 5 bitplanes with a 32-colour palette each (89.73 % of the bytes, dated December 1994), an 820-frame intro, a studio whose name is on the disc only as twelve pictures, a PC's PKZIP whose two members are the disc's own files, and three clocks in one directory. It is the fourth disc stamped on the afternoon of 21 December 1992 — by Myth's preparer, Myth's ISOCD 1.04 and Myth's 50.000000-MiB hole — and the first on which the stuck clock is proved from inside the image: a volume cut at 15:14 indexes a directory written at 19:17 the same day, a second day begins fourteen seconds after the first, and 161 of 162 records carry an even second. The boot is a seven-byte script, a 440-byte hunk that reads the same 99 KB file twice through dos.library, and a raw loader that copies itself to $28000 and turns out to be a four-device library. Akiko drives the CD and the NVRAM through base registers, and the chunky-to-planar port is untouched — checked, for the first time on any of twenty discs, in the register-relative form an absolute scan cannot see. Nothing on the disc is chunky.
The disc image, the extracted files, the unpacked files and every render stay out of the repository; the chapters cite the owner's confirmation of the two renders that were sent (a car head-on and mid-rotation) and of two screens. notes/ holds the tool outputs the chapters cite, checked clean of paths.
