From Dom's Discord:
in order to get retroarch retail you must fill out https://forms.gle/WCqB1fMXhsGx1MzU8 by 8PM GMT Friday everyone who fills out the form will get Retroarch on retail for free this will be the last time Retroarch will be available on retail for free for a while as I don't have the time to really operate a giveaway like last time anyone who had retroarch on retail in the past has been automatically whitelisted too.
once whitelisted: Just enter the code G64V4-DWHR2-PFCKM-FW62W-MX29Z on your xbox
or go to the following url with the account you used for the email:
http://go.microsoft.com/fwlink/?LinkId=532540&mstoken=G64V4-DWHR2-PFCKM-FW62W-MX29Z
then on your console whilst on your console open edge and goto the following page and select retroarch:

I have added a separate ppsspp with Dom's custom store:

Is the white listing per account or per console?
