Your diagram and info is hella interesting!
Now to the questions ^^
1-Do ya know if this mod makes the vga signal better than this vga box?
2-What is the best shop to buy all these stuff? I have no electronics knowledge and so I would be very gratefull if you could give me that info.
3-When your running a DC game, do you have 2 black bars on each side of the screen, or can you play full 16:9 with no black stuff? Same question for 4:3.
4-I would like to do, or ask someone to make me a Digital audio mod as well. My question is, can I use VGA and digital sound at the same time?
Thanks in advance!
