Emulator Issues #8538
Contra / Castlevania Rebirth don't boot in Dual Core mode.
I don't know if this warrants a report since the Dual Core option says some games might not work with it, but games like Contra Rebirth and Castlevania Rebirth don't work with that option enabled.
In Contra, it doesn't go past the title screen, and in Castlevania it doesn't load the first level.
In case it is important, I am using windows 7 x64, i5 3rd gen. Last version I tried it was 4.0-6068.
