Hacking Red Screen

[hackotedelaplaqu]

Hello,

When I run Metal Slug Anthology with Gamma rebooter (Disc Channel) the screen goes red.
This already happened to me with some NTSC isos but here I'm playing a PAL Game on a PAL 60 system (RGB scart).

It's no problem because the game runs smoothly with Gamma Launcher but I'm only curious and want to understand this strange behavor.

If it's of any help : the game is patched on IOS249 with Wanin's Iospatcher (thanks to Wiipower Soft mod compatibility guide).

red screen = YUV output on RGB scart cable
YUV is output when Video Mode is progressive or NTSC interlaced
either use composite cable/component cable or force the video mode to EURGB60 (PAL 60Hz)

Indeed, I must Force PAL60 with Gamma Launcher.

But isn't that game (PAL) meant to display fine in EURGB60 video mode ?
