This does not work for me. When I try to run the game in patch mode I get two black screens, and in clean mode I get two white screens. The linked patch doesn't change this.
EDIT: IT'S WORKING NOW.
For those of you still having problems, these are my stats.
Supercard DSTWO
Kingston 4gb Micro SDHC
EOS 1.08 with that system3.dat file linked above
Golden Sun Dark Dawn lolcatz dump
The problem was the dump. I think my first one was from ==NO-NO SITE NAME REMOVED== or ==NO-NO SITE NAME REMOVED==, no idea what dump it was, nor do I care. It's working now.
EDIT2: Oh that was my bad. Forgot.
