Roman,

When I scan my CHDs I get

Cube Quest [folder: cubeqst - size: 154kb]
no or corrupt chd header/sectormap: cubeqst.chd [chd-md5: d2e6010f9b9d36ba50664096ec331f8d] [chd-sha1: 5266a0a43963628464fac1719e1cefec627042a4]

It passes a MAME scan & plays perfectly.

Then I get

Area 51 / Maximum Force Duo (R3000) [folder: a51mxr3k - parent: area51mx - size: 2mb]
missing but fixable (-> area51mx) chd: area51mx.chd [chd-md5: fce1a0954759fa22e50747959716823d] [chd-sha1: 7e629045eb5baa8cd522273befffbf8520828938]


Again I scan it with MAME it passes a scan & plays perfect. Can you explain this a little? If I missed it somewhere I am sorry in advance

Thank You
