Did you manage to figure this out?
Below was posted on Reddit r/originalxbox
Recently restored/tsop'd a 1.1, all setup and ready to go. Auto login checked, however when booting you see the profile select screen for a fraction of a second, not a big deal but is there a way of removing it?
I have a 1.4 I did years ago, I removed the login screen back then but can't remember how.
I found some old instructions from the man himself...
"Edit Q:\USERDATA\profiles.xml and change line 3 from <useloginscreen>true</useloginscreen> to <useloginscreen>false</useloginscreen>
Now all you need to do is change the skin to Profiles skin & you're done." - Link
But not sure what "Now all you need to do is change the skin to Profiles skin & you're done." means, as I can't see an option to change the skin. Or is this an xml edit?
I'm sure this is simple and I've overlooked something, any help would be appreciated. Thanks.
