Yieks...a standard scan (without sha1 and full chd decompression) takes 1 minute here and when everything is in the diskcache only 8 seconds ;)


> Did it check for any reason only SHA1?

MAME only supports sha1 and crc32. CHDs do have also an additional md5 value in the header.

My samples datfile is based on the MAME's sample output. No idea what Logiqx uses.

No. Use Logiqx's mamediff tool instead.

You can always use Scanner->Scan Results Tree window->Set Information (button bottom left) -> Export

Simply hit 'cancel' during a scan and ignore the prompts. You can go on later then. Ok..currently this means you have to keep you PC on and don't quit cmpro...
Not a bad idea to provide some 'pause' functionality where you can turn off your pc. However nobody knows if someone scans 50% then pauses, manually changes parts of the 50% and continues scanning....
Normally fastscan is for this....one full scan, afterwards only fastscans..


You don't need to do a full sha1 + chd decompress all the time...this is overkill...you may want to do this once a year or so....
