A raw Xbox DVD image contains, besides the game, padding data that makes it unreadable by emulators. The format xemu expects is called XISO: the same image, stripped of that padding. Conversion happens in two steps — extract, then rebuild.
Online converters exist (such as
xiso.antangelo.com), but they do not work in every browser and, in our testing, the resulting image is not always usable. Prefer the local tool described below.
Go to extract-xiso-gui, click the latest release under Releases on the right, and download the archive (with or without installer). Extract it: the extract-xiso.exe executable is inside the extract-xiso-gui folder.

extract-xiso.exe.Extract mode.Input, select the disc image to convert.Output, pick an empty folder.Go ! and let the extraction finish.Create mode.Input, select the folder you just filled.Output, choose the location and name of the final image.Go !.You end up with an .iso file in XISO format, ready to be copied into /recalbox/share/roms/xbox. Refresh the game list and the title appears.
Converting to XISO also shrinks the files noticeably: the padding removed often amounts to several gigabytes per game.
