# stf-sharc: reconstructing Sega Model 2 SHARC microcode

> stf-sharc reconstructs and annotates the two ADSP-21062 microcode images used by Sega Model 2 hardware. The assembly documents COP math commands, GEO display-list commands and FIFO exchanges; the author reports that both images reassemble byte for byte to the ROM.
