Support Request: I just downloaded the Rune Factory 2 (U) undub version. The intro works fine, then I started new game but only got black screen with the music still playing.
I opened the same ROM with Desmume 0.9.10 Windows version and it works fine so I think it's not because of the ROM.
(I’m using Mac OS X 10.10.1)
Please help. Thanks in advance
