Upgrading to Stellar XboxHD+


How difficult is it to install?
Stellar should be a drop-in replacement for existing mods in most cases. For unmodified systems, a 2x8 pin header will need to be installed along with the QSB flex for 1.6 systems.

Is this compatible with the XboxHDMI/XboxHD+(v1)?
Yes! A simple adapter kit is required.

What can the MicroSD card be used for?
Currently, the MicroSD card is used for additional storage of BIOS images, log files, etc with future plans to allow for mounting virtual HDD images (for non-HDD setups).
