Then the problem becomes not being able to boot games. The original/factory XDK BIOS did not allow me to boot retail nor homebrew games.
I currently have the XDK hooked up to my 42" LCD TV via Component cables (with the Xbox HD AV pack) and it displays 4:3/480p just fine. I can "stretch" the image as a function of the TV, but then the games look distorted. As I said previously, I can change the resolution of the Launcher to 1920x1024, but the setting does not appear to persist for the games, once booted.
I think I might be confusing the functionality of the BIOS versus the dashboard/launcher. In the XDK Launcher, I see no option to permanently change the system to 16:9 like I suspect there is in a retail xbox's dashboard. Should I be pursuing a non-XDK dashboard/launcher while still using the gueux bios?
Another thing to note... when I run Avalaunch, it runs in 16:9/1080i (as does XBMC), but under "options" it says that widescreen is disabled (presumably for games). I go to change this and it complains that the HDD is locked. I unlock the HDD and try to change it again, and it whines about something to do with "all writing to EEPROM disabled."
I'm not convinced that Avalaunch interfaces with debug eeproms right, i've seen multiple errors over the years.
In order to set a debug xbox to use widescreen, from the XDK launcher select the retail dashboard and change the settings from there.
As i said before, i'm not sure the Gueux bios supports anything other than composite (Standard RCA cable) connections. I know it doesn't support S-Video. I don't have a HDTV to test this with so i'm not sure.
In order to run retail/homebrew on a debug without the gueux bios, you can convert the xbe using dexbe. Just open the application, open up the xbe on your pc and hit patch as debug (just close the application from there, do not save the changes).
