thanks for the fast reply. What do you mean by: "...and picked blazstar in the internal UI. After picking a BIOS the game loads and runs fine for me"
When I hit Enter or on selected "Blazing Star" entry or doubleclick it, the message about missing roms/CHDs appears. How do I "pick a BIOS"? the neogeo.zip is inside my roms-folder. As I stated: starting blazstar via command line works. Am I having a handling error? How do I pick neogeo as necessary bios in UI?
