NRG format file support

[MrPepka]

I have some game CD images in nrg format. Is it possible to add support for this format in 86Box? I checked the internet and although there is an article about this format in Wikipedia, I do not see documentation for it (although maybe there is one?)

I don't think Nero's NRG format is documented at all from what i can tell, but as an workaround if possible convert the game CD images to something like bin/cue (if it has CD audio tracks) or .iso if it's just a data disc, and then you can mount it in 86Box like normal.

There is some documentation on wikipedia, albeit not complete: https://en.wikipedia.org/wiki/NRG_(file_format)

Some code here too: https://github.com/sysprogs/WinCDEmu/tree/master/ImageFormats

More importantly, WinCDEmu has code for CloneCD and Alcohol 120% Images. These image types are mostly encountered when copy protection goes beyond what can be stored with bin/cue files. I don't know how good the WinCDEmu driver is when it comes to reading those images (whether copy protection bits are properly represented), but it would be a good starting point for an implementation within 86box.
