[Openchrome-users] only NTSC modes in VT1626 TV-out modes? -> need PAL

[Roy Thompson]

I've been tinkering with this myself (PAL on an EN12000E).
I've managed to get 720x576 over-scan more or less working.

I copied over existing 1622 entries and merged in stuff from the via 
console driver,
which has all the mode entries for 1625, although in a slightly 
different form.

Is this the right approach to take?

I also tried 640x480 under-scan, but not sure whether that really works 
in this patch.

Attached is an svn-diff from revision 201

Be warned this includes a few changes to via_mode.h and via_id.h also 
that someone else
posted to the list a few weeks back for EN12000/CN700, sorry, I've 
forgotten who!
I am not sure if they are needed as well or not any more.

Anyway, it displays more or less the correct looking image. :-)

I've got this test card image from the BBC website, which is great for 
testing over scan
mode (http://www.haematic.org/bbc720x576.jpg).

cheers,
Roy
