Will officially downloaded OG Xbox games work on modded 360?

Using badavatar. I've partitioned my drive, added the compatibility files to Compatibility on HddX, and I'm using Xefuspoofer. My officially purchased and download OG Games are in Hdd1/Content/00000... (etc.) and they won't run. is there a step I'm missing? will these versions of the games work, and will moving them somewhere to HddX help?
