Since Gamecube resolution (at least for interlaced modes so I understand) is 640x528@60hz (50hz for PAL), how do I go about adding that modeline?
I've tried a lot in the past to understand how these modelines work but I just can't figure it out.
I'm using the "super" resolutions (I think, it's been a while) from when windows 7 support was added (about UME 0.153?).
-
Add that mode into ReslList.txt and run VMMaker:

I did try that but it says it's redundant ???
-
Attach your ModeList.txt file here.

It's in the modelist.txt but it's still dismissing it as being redundant ???

Ok I see, you simply can't get 528i@60 with 15 kHz, it's clearly out of range. You must create that one as PAL (50 Hz).
-
Oh right, yeah I just changed it to 50hz and it added it fine.
It must work in 15khz though or else gamecubes wouldn't work on US TVs, is it just a limitation in the graphics card?
-
Ok now I have played with it in arcadeosd I can see it's way out of range. I still don't understand how US consoles can display it on a normal TV, or PAL consoles displaying 60hz.

640x528 is the internal resolution. this is changed depending on if you then are running pal or ntsc
"The internal resolution of the GC/Wii is 640 x 528. This is the resolution that the game is rendered at whether it is a PAL or an NTSC game. A PAL GC/Wii will then stretch that to 768 x 576 while an NTSC GC/Wii will stretch it to 640 x 480 before output.
Dolphin stretches it to whatever you set your fullscreen or windowed resolution to be. It doesn't use the PAL or NTSC resolutions as output unless you specify it yourself."

Well that makes a lot of sense. The PAL resolution looks much more like the real thing and Dolphin actually runs it at 50 frames per second too.
I still get tearing but I guess my system just isn't up to the task. Thanks all, Calamity, your support is second to none.
-
Tearing will always visible unless Dolphin has double/triple buffer or could sync to vertical freq just like MAME.
That reminds me that is time to test new Nestopia in my arcade PC.

perhaps some useful information here:
