The link is supposed to go to my site where you can download it there: MUGEN Coder. I'm not the admin here, so I can't do it. So just go directly to my site from link above and you should be good.
@dingo & @AK_Sasuke: There's nothing to fix in that regard. You'd not see those errors if you were using MUGEN 1.0. I'm not going to downgrade my characters to a deprecated system, so just note that. I think it's time for you to switch.
