As I posted earlier, you will find more 'help with SCI than AGI. A lot of the AGI resources on the web have been lost, including the Wiki. The AGI and SCI communities used to coexist on the old MegaTokyo board, but split apart after that board closed. The AGI community ended up on agigames.com, which had resources, a forum and Wiki, but since has closed. Cloudee made room here for some of the AGI tools, AGI fan games and added a couple of forums here for AGI, but the people that really know AGI are long gone. The SCI community and resources have endured.
SCI0 has EGA graphics and can use PC speaker sound. It has lots of tutorials, resources and better documentation.
