Reading CD data

There are currently three ways to purchase Redguard: The Original on CD, the GOG version, and the Steam version. The CD version stores music and cinematics on the play disk (aka disk 2). The GOG and Steam versions store that data in a disk image in the game's folder.

Ideally we are able to support both methods. While it would be easy to access the CD data from the original (once it's in the Cd drive), the disk image is seemingly not as easy to access, and possibly has to be converted by the player after the installation process. Obviously Dosbox has some smart method to read from the disk image directly, otherwise the GOG/Steam version wouldnt work, but we dont know how it does that yet.

Right now, the best way to open the disk image is this process:

1. Install 7-zip, and a plugin that lets 7-zip open disk images: https://www.tc4shell.com/en/7zip/iso7z/

2. go to Redguard's directory, locate the game.ins file (it's just a renamed .cue file) and make sure that game.gog is in the same folder too (this is the .bin disk image).

3. Right-click on the game.ins file, and go to 7-zip -> Open.

Then you can see the files directly through 7zip and copy them to a new folder for easy access.
