Hi again.
Yes, I did launch Emu-finder, loaded the mame0211.xml, launched the Emu-finder again and replaced with new results, then tried to print the Softlist.
I am using mame0211b_64bit, mame0211lx taken from mamedev webpage.
When I tried to print softlist for the first time, I was using QuickPlay 4.6.6 with MameUi 0.211, I had everything deeper into my hard disk, bunch of symlinks... got that error, then I did set up everything on Mame 0.211, same thing happened. Then I redid everything on temp dir without any symlinks... using clean install of quickplay and mame, same results.
Emu-Finder:
Loaded XML:
Second Emu-Finder: (selected all and replaced with new results)
First print Softlist: (same list and error I've posted before)
Second print after copy: alphatro_cart.xml to alphatro_cass.xml, squale_cart.xml to squale.xml:
Third print after copy: apple2_flop_misc.xml to apple2_misc.xml

At this point list is pretty big, perhaps complete, I have to check if there are more hash file missing.

Sorry to say but at the moment I don't have any other version of mame, previously, I was using QuickPlay 4.1.2 with some non mame emulators + pack of rooms, like nestopia + nes roms, visualboy advance + gba roms, outside of QuickPlay I had MameUI + mame roms(non softlist). Recently I just updated my Roms, I believe from 0.172 to 0.211, and got SL Roms for the first time... may be hard to find early versions of these roms... later I will try to find something.
