The project would also incorporate other parallel efforts to make game emulators for other adventure games. Games from Sierra Online were of high demand for the project, requiring them to emulate the Adventure Game Interpreter (AGI) and the more advanced Sierra's Creative Interpreter (SCI) engines. AGI support was added in 2006 by incorporating efforts from the Sarien project, but efforts for SCI support were hampered by the parallel project, FreeSCI. Though both "ScummVM" and FreeSCI aimed to reverse engineer the workings of SCI, FreeSCI had stated they took a more clean-room approach to avoid any legal question about their reverse engineering, and believed the "ScummVM" project had run afoul of some of Sierra's approaches and thus were hesitant to work together. However, FreeSCI began to languish in interest compared to "ScummVM"; after a developer took it upon themselves to make the FreeSCI engine work in "ScummVM", the FreeSCI saw more participation in their project, and they agreed to merge their efforts into "ScummVM". Initial SCI support was subsequently released in a 2010 version of "ScummVM".
