My Gamecube does not support progressive scan

Postby Ripthorn » Sun Dec 03, 2017 4:51 pm

Kinda true...

Here's the thing: if I boot a game and chooses progressive scan, the gamecube just hangs and display an image with the half brightness. Interlaced mode works fine, but if I boot the swiss first, leave the force progressive off and try again the progressive mode selection, progressive scan will work fine :|

Right now I only own one USA game (Zelda WW), So I can not test other games to see if this problem repeats. All my other games are Japanese, they all work in progressive scan through Swiss.

A strange thing that I noticed is that the Swiss always force NTSC color in composite and s-video, if I boot a game without it, the system stay in PAL-M.

My GC is a DOL-002 and I use a D-Terminal cable with RCA adapter.

So does anyone know of a possible fix for this?

This is normal for PAL-M, post-launch games will crash on progressive scan. Just use Swiss.

This is really weird, I thought only the PAL gamecube had this problem, not PAL-M. Now I can not use RGB and neither 480p :cry:

I know, I can use Swiss but I hoped I would not have to use it for everything, It's a pain in the ass to always swap discs.
Does the GCvideo or force progressive scan on modchips will help?

GCVideo does nothing for software problems. Modchips are less compatible.

Oh well, it seems to be possible to put Swiss on Qoob Pro flash memory, better than swap discs.

Anyway, thanks for the help, Extrems

You should use iplboot instead of flashing Swiss to the Qoob. You can also flash an NTSC IPL to it.

Can you point where I can get more information about the iplboot and IPL flash?

https://github.com/Streetwalrus/iplboot
You can find the flashing tool in the Qoob thread with the latest official update.
