# AGS 2.x Decompilation: matching the Adventure Game Studio runtime

> AGS 2.x Decompilation reconstructs the Adventure Game Studio runtime engine from reverse engineering, prior source and instruction comparisons. Its build supports DOS through DJGPP and, from version 2.03, Windows through MSVC. The author reports version 2.00 complete and a demo game playable; later versions remain in progress.
