(re: re: re: Ken Williams Q&A) There are new interpreters for Sierra’s games, such as Sarien and NAGI for the old AGI games and FreeSCI for the SCI games. Unfortunately, FreeSCI is not nearly as developed as ScummVM. It has some sound issues and only has SCI0 (EGA) support. Rudimentary support for SCI1 (VGA) game is being developed in Glutton, an experimental branch of FreeSCI.
DOSBox is a solution for many Sierra DOS games.
