Alien Soldier: byte-identical Mega Drive cartridge reconstruction

Alien Soldier source reconstruction rebuilds the Japanese and European Mega Drive cartridges from shared 68000 assembly and a separate Z80 sound-program source. The author reports byte-identical builds from user-supplied ROM dumps and provides format documentation, content-editing tools and a MAME attract-sequence check.
