Hello,

I just just finished installing the expander and when i tried to use the 2nd pre-installed rom(rom d), there's just a tiny hiss noise. Maybe the rom is just blank but when rom d was selected the ph sort of glitched out(no audio from other roms) until i turned the power off. Is this normal behavior for a blank rom or is it something else?

Please help.

I didn't find the right solution from the Internet.
