Therefore.
I see a new mame 0.272 it's released. And i go to update my personal collection of mame titles and i ever used (i thinks in correct ways) clrmamepro.
Today i have try to use the newest Scanner and Rebuilder.
First of all i have used the scanner whit my collection:
- add folder "D:\Emulatori\MAME\Roms"
- set a Backup Folder
- Add mame.exe path
- Click on "New Scan"
After about 30 seconds (it's very much speed respect the clrmamepro scanner.... omg

it's obtain a very large xml files whit entire result.
It's be saved on "D:\Emulatori\MAME\Tools\clrmame_007_014\scans\27a5041a-listxml.xml"
For the UI i see i can filter the view.... i have selected only "Partly Wrong" and i have exported the list on clipboard to obtain a txt whit detail and my missing file and obtain somethings like this:
0.272 (mame0272)
bumba [Bumba (bootleg of Head On)] [cloneof: headon]
fixable missing rom: 3.a6 [crc: 461c2658] [fixable via: D:\Emulatori\MAME\Roms\headons.zip\3.6a]

fixable missing rom: 2mm.u2 [crc: b94ef7ab] [fixable via: D:\Emulatori\MAME\Roms\verbena.zip\2mm.u2]
etc etc
After this i have downloaded all missing files....... and i will try pass to use rebuilder.
- Copied all downloaded files in a folder:
D:\Emulatori\MAME\Tools\clrmame_007_014\Rebuilt. Add this path on "Input path"
- Set the output path on "D:\Emulatori\MAME\RomsTest"
And click on Start. But it's nothings append. On log it's appear an error.. it's say somethings similar:
2024-11-30 12:51:50 error I/O backup path is required
2024-11-30 12:51:50 info Done, overall time: 0 seconds
2024-11-30 12:51:50 error errors occurred, please check log
But i have set the backup path.... what am I doing wrong?
Why are no files being recreated?
