So after seeing the xbox upgrade worklog off @bennydiamond i wanted to try the vga mod myself. (Here's the worklog: https://assemblergames.com/threads/...rklog-and-reference-for-future-modders.44219/ Made a small smd version off his sync amplifier (Great work there btw!). Installed it and voila great 5v sync signals. Made an external breakout board for the VGA and audio-outs and soldered everything together. Next step flashing a vga bios and testing it! Turned on the TV and the Xbox.... Sync is working but i got a bad green tint. Back to finding out what's wrong. After realizing the Xbox allways outputs sync on green (Thanks again benny!) the problem should be this damn sync signals messing with the green data line. You could also say my TV is the problem as it can't life with the sync on green but it should work on any TV in my oppinion! Thought about clamping those sync signals using electronics but every modification off the signal would alter the quality! Wouldn't it be better to just not have these sync signals mixed on the green data lines at all? And well Xbox Linux distributions can already do that! They can output flawless VGA by setting a register off the Video encoder to not mix the sync on the green signal line! My question is does anyone know what would need to be patched to get an Xbox bios to send these i2c commands to the video encoder? Or would that not work at all? Wil upload a few shots off my VGA install later today.
