Although the changelog on the Wiibrew page says it has been fixed, I still cannot load ROMs from USB with this version of the emu. Ever since the new GUI was implemented, it has been broken for me, and the only way I can play MD/Genesis games from USB is by using 1.3.1

Anybody else having this problem still?
