I rechecked the screenshot code.. it is dumping video registers in the CC000000 memory area.. that's where games built against the Wii/Gamecube SDK store their video data to. Unfortunately libogc does not need to do the same.. if libogc does not store video registers there, WiiRd cannot locate the YV12 picture in memory...
Quote from Link on Wiird forums, suggesting that if you modified the screenshot code to dump the video registers from the CORRECT location in memory for libogc, you could screenshot homebrew. Dunno where that location is, or where the code is that would need modifying, but there it is. I don't see why someone couldn't do this, one of those far more experienced than myself. i.e. in theory it IS possible to screenshot homebrew, just the software doesn't exist for it right now
