Aspect ratio correction not working in PAL60 #145

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Using a Wii set on PAL60 (480 lines)
2. and setting the video mode to aspect ratio correction
3. with the video mode on auto or PAL60

What is the expected output? What do you see instead?

The aspect ratio should be correct as it is in 50Hz mode. Instead, the
picture is too tall (the black letterboxing bars aren't big enough) and
circular objects are obviously not circular.

Does this issue occur on VBA-M r781
(http://vba-m.ngemu.com/vbam/vbacompiles/msvc2008/VisualBoyAdvance781.7z)?
If so, please report the issue to the VBA-M forum.

Pretty specific to the Wii version I think.

What version are you using? On GameCube or Wii?

Wii

Are you using the official build (from the downloads page or auto-update)?

2.0.5 downloaded from TehSkeen.

Please provide any additional information below.

I have a guess as to why this is: PAL60 actually runs at 480 lines instead
of 576 like PAL50 so a different value is required somewhere in the scaling
code. Possibly the same value that is used for NTSC which I believe is also
480 lines?

The obvious solution would be to run the Wii at 50Hz except for some reason
the emulator performance suffers massively in 50Hz (and stability seems to
be affected by it too).

This could be as simple as using the same aspect ratio correction as NTSC as 
PAL60
and NTSC are the same resolution. As far as I know, the only difference is the 
colour
encoding.

It works fine NOW, it was broken this time last year though. :P
