Record marked as obsolete and not updated for a long time.
The kmg file extension is associated with development applications for the Sega Dreamcast. The file contains an uncompressed picture image for use in Dreamcast software.
The Sega Dreamcast was a 32-bit video game console released by Sega in 1998 and discontinued in 2001. It was Sega's final console. The KMG format is now obsolete.
A kmg file generally cannot be opened by common desktop image viewers. It should be opened with the Dreamcast development application or tool that created it, or with another tool that explicitly supports this format.
If the associated development software is unavailable, the file may not be viewable directly on a modern desktop system.
The image may be exportable to a standard format using compatible Dreamcast development software, if that software provides an export function.
