The profile described an Odin edition no branch carries any more. At the pinned commit core.c embeds VXTBIOS, VXTX and the EGA BIOS, never asks for the system directory, and writes its FreeDOS image to the save directory; an INI machine can load a ROM from a path it names.

|
|
VXTBIOS, the VXTX disk extension and the EGA BIOS are embedded. A machine
|
|
described by an INI file can load a ROM from a path the INI names, read
|
|
through the frontend VFS as written. With no content the core writes its
|
|
embedded FreeDOS hard disk image to virtualxt_default.img in the save
|
|
directory and boots it.
