Hi!
I have a little problem, only slightly minimig-related.

I just got a tiny little video projector, which happens to have VGA, HDMI and Composite-AV.
When i connect the minimig to VGA, i get in both modes - 31kHz and 15kHz - a very good picture. I was very surprised that this little guy accepted the 15kHz signal without any problems, so i tweaked the SCART-Box i made for the Minimig a little bit. I added a switch to change the connection between VGA-Pin13 and SCART-Pin20 to SCART-Pin19.
Then i tried this cable with my PS2, my XBox and my SAT-Receiver, all of them are set to give out RGB signals. Nothing. No Picture.

Any Ideas?

edit: I just tried it with my A1200 and RGB to SCART cable. Works just fine.

When Minimig (3.3V) and original Amiga (5V) hardware works, I don't have any idea for the other devices.

Maybe the cable is not 100% wired-up for the other gaming devices.
It it working directly connected to a TV-Set?
