If you have files that unpack to a Blu-Ray structure like

\BDMV
\CERTIFICATE

but you don’t have a Blu-Ray recorder, you can easily still play the corresponding Blu-Ray disc:

(1) use Nero Burning ROM to burn an image .nrg file of a Blu-Ray compilation consisting of the files.

(2) mount the resulting .nrg file in a virtual DVD-ROM using the free “Daemon Tools Lite”.

(3) install the free “K-Lite Mega codec pack”.

(4) use the provided free “Windows Media Player Classic” to open the “DVD”, even if it is a mounted Blu-Ray.

And that is it.
