Idk what I did wrong suddenly. Please help.

Hi,

The "not found" message can only mean one thing - whatever you are trying to run is missing files.  Somehow the files have gone missing.

Doing a quick Google search for those ROMs I was able to immediately find the missing file.  I suggest doing the same and adding the files to the missing sets, then trying CDi again.

Sorry, I do not know what the rules are for posting ROM links and most websites frown upon it (for good reason), so I'll leave it up to you to find those files.

Hope this helps
