RealArcade Client XZIP2 (*.MEZ / *.RGS, *.XTR)

I would like to figure out how to decompress content from RealNetworks' legacy RealArcade game client that only it can open. I see a header of XZip2.0 but I cannot figure out anything beyond it. Research on the company implies they bought NetZip and updated it (at least for RealArcade) to use a proprietary algorithm and/or encryption.

RGS files won't be provided as they are protected game installers with their protected executable and content which I'm not sure if they will be OK to distribute here. XTR and RGS really only have a package header and XZip2.0 content, so realistically it's the same format. The file rngcinstallengine.dll in the client has the checks to verify, hash and logic to read the header, I don't recall about actually decompressing it. Note I use v1.20.1256 of the client.
