640x528 Gamecube's Internal Resolution?

Post by Midori » Mon Oct 27, 2014 12:58 am

I recall reading on Dolphin Emulator's forum a bit ago that the internal resolution of Gamecube is 640x528 but the conversation ended up confusing me as I thought it ran things native in whatever region, NTSC 480p etc.

Is the resolution really 640x528 and not 640x480? thanks.

The GPU draws on an embedded framebuffer. This framebuffer has a hard limit of 640x528 in RGB8Z24/RGBA6Z24 modes, 640x264 in RGB565Z16 MSAA mode and 1024x640 in YUV 8-bit 4:2:0 mode.

The framebuffer's contents go through a copy pipeline to main memory to be scanned out.
