1. What's an IP.BIN?
When the Dreamcast boots a GD-ROM or CD-ROM, it reads two things from the disc before the control is passed to the program. First a bootstrap is loaded from the reserved boot area (sector 0-15) of the last data track. This strap is called the "IP.BIN", although it of course does not have a file name on the disc. Among other things, the IP.BIN names a file in the ISO filesystem of the disc that contains the actual program to run and load. This file will here be called the "1ST_READ.BIN", although any name is possible as long as it is correctly specified in the IP.BIN. When the 1ST_READ.BIN has been loaded, control is passed to the IP.BIN, which will in turn pass it to the 1ST_READ.BIN.

2. What's an IP0000.BIN?
The IP0000.BIN file is present on every Dreamcast disc, and contains information about the software on the disc. The meta information is repeated in the 16 first sectors of the first Mode-1 track on the disc (the area reserved for boot code by ISO9660), so it is readable in a normal CD-ROM player. For the Dreamcast to consider a disc bootable, this structure must also be duplicated in the high-density region, together with some standard bootstrap code and an additional region enforcement layer.

3. What's an MR logo?
These are the pictures displayed during the licensing screen. For normal IP.BINs, the maximum size of an MR is 8 KB (8192 bytes). The maximum amount of colors allowed is 127 colors and it's resolutions mustn't be greater than 320x90 pixels
For a transparent look in the MR, use the hex color C0C0C0.
