Kronos currently supports magnetic scrolls games; ive not had time to release a zmachine module for infocom type stories, but stevem ported Frotz so you're good there too. Every MS game is excellent btw - try Guild of Thieves or The Pawn or any of them . Scummvm should be checked as well if you want graphical games
really thanks for replying but i cant find these file types only .rsc
i went to the memorial site but none of them had mag or gfx i have some with gam and .z5 and .z8 .t3 and .blb
