Byte-level study of Mega Man (PC/DOS, 1990): 29 loose files, 346,995 bytes. Unpacks the EXEPACK'd executable, identifies the one PackBits variant the whole game uses, and closes .SCN/.BLK/.FRM/.STA/.BIN by arithmetic. Renders the credits (the object's only attribution) and recovers the twelve copy-protection answers.

Measurements of Simulman V (MS-DOS, Simulmondo, Bologna, 1993): 120 files, 2,056,643 bytes, zero compressed blocks, one mtime that is wrong by three years. All sixteen unknown formats derived from the bytes; the year is drawn in pixels; one executable is byte-identical to 1000 Miglia's. Recorded media: 0.0000 %.

Format and engine documentation for Prince of Qin (秦殇, Object Software, 2002): the Lib 1.01 archive, xbm sprites, SoloMap terrain and DLGTEXT text containers, with verified Python readers.

Byte-level study of Mega Man 3: The Robots are Revolting (PC/DOS, 1992, Rozner Labs / Hi Tech Expressions): the ZIP read as an object, twelve-bit LZW, one byte per pixel, four undocumented formats, and the 1,855 bytes it shares with the same studio's 1990 Mega Man. 19 chapters, 13 tools, every figure with its command.
