Chances of this happening are slim. If a debug game failed on XBR it's probably because it was relying on debug functions available in a dev that wouldn't be on retail. Although freeBOOT removes the protections on a retail console, it doesn't add any dev support. In the end, it's still a retail console with retail firmware. If you want to get all dev games running on a retail you would need to build a freeBOOT or XBR image with source files from a dev NAND, not a retail NAND. -hl718
