    How to replicate the problem: I can launch Gunstar Heroes for Genesis just fine, but every other Genesis ROM that I load will give me a blank screen and then go back to the menu. I've tried Road Rash, Sonic the Hedgehog, Sonic the Hedgehog 2, Sonic the Hedgehog 3, Shining Force, and none of them load. The log pasted above is the result I get and it seems to indicate that libreto is looking for a BIOS file for the mega drive. I searched the forums for others with the same issue, but nothing came up. Any suggestions or solutions?



  • After much hair pulling and searching, I managed to find the solution to my issue. All of my ROMs except for Gunstar Heroes was a 0kb file. Once I replaced the empty files with good ones, they all played perfectly.
