OK, sorry for the missing Info here... I have it on the Ez-Flash Omega. Other GBC Games that I have tested are running good so far. I tried to convert the Konami GB Collection Vol.4 with Goomba color, but it doesn't start also... So i have the same problem with the Collection Vol.2, while Vol.1+3 are running great. To check if the roms have an error i loaded them into VisualBoyAdvance on my PC and they are running great. So i have no clue what's going on here. Is there a way to extract each of the 4 games of that package to run them stand allone? I wish i could extract Castlevania II color. I saw that there is a hack that let you directly boot into Castlevania II without loading up the menu where to select which game you want to play of the 4 and i have tested it but it doesn't work too. :-(
