RadioRealism Alpha V1 1.2

I look forward to trying this out

where are the backup files? please

Apparently, You did not take the time to completely read the included documentation and install instructions.  It is stated VERY clearly in the documentation for Radio Realism, that you make a backup of your own files before installing  - They are not included.  

Because the original files Radio Realism replaces are not mine and belong to G17 media, it is against the terms of use for LSPDFR to redistribute any files that belong to LSPDFR and G17 media. Therefore, including backup files was not possible to offer and for me to abide by the terms of use for LSPPDFR.

If you do not have the audio files and need them, simply redownload LSPDFR and copy the resident folder over
