heya. yeah. havin no luck getting this chd convertor to work. i'm gonna keep trying, but so far, no dice. i can't even tell which version im running because the thing just crashes in wine.
*EDIT
just got it to work. finally found a chd converter that worked in wine with gdi files. first one tested was ikaruga which came out to 73 mb (as you said). this is insane. just converting the 4 dreamcast games on my retropie to chd should free about 2 gigs.
thanks again
