ok, mame artwork as an example:
1) download the mame artwork dat here:
http://mrdo.mameworld.info/mame_art/mame_artwork_dat.zip2) drag'n drop this file into cmpro's profiler window and select [Profiles] as sutiable place for the dat. Then double click the newly created profiler entry in this tree branch. Select "Default" in the next prompt telling you that by now no settings exist.
3) go to settings and add a rompath which point a folder where you put your artwork zip files.
4) go to the scanner and hit scan. It will tell you what's wrong. If you want to get them fixed, you need to turn on the fix options.
If you want to scan flyers, snapshots etc, then be aware of the fact that the dats for such 'art' stuff is usually a 1-set dat listing all single pngs in that 1 set. Then you need to think a bit how to setup the rompath...but actually I explained that in the last post.
