Is the original xbox madden 07 dlc available somewhere online? Is it a backwards compatible 360 game? Depending on the type of data that the dlc contains, you might be able to build an iso containing the dlc that could work on a modded 360?
The og xbox madden 07 didn't have dlc. The dlc for the 360 madden 07 was data you downloaded, so not just an unlock key. I was able to find the xcp files for them, but they need decrypting, and I don't think that is possible right now.
Just seems like if the ps1 has a aftermarket memory reader and the dreamcast has a vmu, then everything after probably is capable of having something...
I always try to imagine this scenario, If Sega hasn't gave up do you think Dreamcast and the Xbox could coexist? Would M$ Still update the Windows CE...
