Black screen when launching games after XboxHD+ install w/ ModXO Lite
I'm having a hell of a time getting this sorted out on my 1.6 Xbox. I have a ModXO Lite that I installed a few months ago and it is working great. Today I installed a Stellar XboxHD+ Standalone & XboxHD+ Legacy combo, booted it up and PrometheOS/Cerbios v3.1.0 are showing fine over HDMI. The XBMC4Gamers dashboard also displays like it did before.
However, whenever I boot up a game or try to launch the HD+ app, I just get a black screen, no audio, and no actual signal to my RetroTink 4k. I have tried disabling some of the AV features in the PrometheOS menu, but nothing has changed.
I didn't install any custom BIOS, as from what I've read, that's no longer necessary with the latest versions of Cerbios. I saw some talk of grounding the D0 pin, but that wasn't in the installation guide and seems to already be covered by the ModXO? Not sure what to try next, any help is appreciated.
