gd-rom

A small go project to maybe dump dreamcast games on linux and windows

Development board for the Dreamcast G1 Bus

The canonical Sega Dreamcast platform checklist, to be carried across documentation pipelines: GD-ROM's two areas, IP.BIN in front of the filesystem, the scrambled SH-4 executable, CRI and Sega middleware, PowerVR textures and the ARM7 AICA driver. A scaffold - every claim is marked [unverified] until a disc says otherwise.

Index of the Sega Dreamcast disc documentation: one repository per pressing, plus the shared GD-ROM platform checklist they feed into. Empty so far - created before the first disc so that disc one has a structure to be filed into. Format archaeology only, no disc images, no game assets.

Sonic Adventure (Dreamcast, 1999, MK-51000) measured from a three-track BIN/CUE GD-ROM: 1ST_READ.BIN is not scrambled, .PRS is LZ77 with no Huffman and closes on 843/843, 17,083 textures, 4,197 ADX streams totalling 5h46m, two ARM7 sound drivers, 244 credited names behind the compressor.

Dino Crisis (Italy), Dreamcast GD-ROM, Capcom 2000: the IP.BIN boot block is 99.69 % shared with the first disc, 276 untagged .DAT opened to the byte, and six languages on a disc where 'italiano' counts zero.
