Using GCDEMU 3.2.6 in Ubuntu 20.04.3.
PowerISO DAA files are mounted and listed in file managers and all files are copied correctly.
If trying access to mounted DAA file using emulators the files are listed correctly, but happen access errors. Only the first files in root folders are read correct, but subfolders not are read doing issues in emulators.
If mounting ISO file using emulators not happen issues. All work correctly.
Tested with DAA files with 6 and 8 GB using normal and best compression both not work.
Perhaps issues not decompressing DAA data in enough time ?
