Agreed: for anyone playing Radiant Dawn on Dolphin, the PAL version works far better. The PAL version is also easier to find online; just search for "Fire Emblem Radiant Dawn PAL" (without the quotes, obviously). The MULTi 5 version is verified to work properly. Yes, I know you want links, but there are legal ramifications to that. Run the search on the major torrent sites and/or look around for a ROM site with Wii ISO images. On torrent sites, always check first for seed/leecher counts, and second for comments. Commenters will often warn you if a torrent is fake.
Save often, as it may occasionally crash. There are one or two places where the game is much more likely crash -- Hard Mode only, as I recall. If that happens, switch your DSP to LLE mode until you finish the level/event.

If you followed our advice and found the PAL version, then add 442272 (decimal) to the code addresses (6BFA0 in hex). Works for most character codes. Windows calculator can switch between hex and dec in programmer mode. Alternatively some spreadsheet editors, such as Excel, can convert between the two using the =DEC2HEX() or =HEX2DEC() forumlae. The offset between characters in the PAL version is 1008, or 3F0 in hex.
