nogba white screen problem

[Sonic riders zero]

hi

im trying to play sonic games on nogba like sonic rush and sonic colors

so sonic rush worked but when i tried to run sonic colors on nogba it gave me an error and said that i need a bios files so i downloaded the bios files and they worked with all games but when i tried again to run sonic colors it gave me just a blue or white screen

please help me

note : this game worked on desmume emulator without bios but i want to play sonic colors on nogba im using EUR version for sonic colours

The game is incompatible with no$gba.Stick with desmume it is the best ds emulator.
