I want to do this, to save space on hard disc. I'm using it with Dreamshell. Usually, I extract the files with gdi2data. After that I'm using: hack3 1ST_READ.BIN 0 And it's working, but some games don't work. They just restart. Games like Draconus, Dragon's Blood, etc. If I extract the files from a working CDI, the same thing happens.
