I have try and use Neo RageX all the while for my neo geo roms,however my friend told me nebula is much more better and i decided to try it.The problem is that i can't use the nebula to play my neo geo roms.I can play all my neo geo roms in my Neo RageX,but only some show up in the nebula list.What do i miss or what do i need to do ?And i have delete away the nebula file,where can i get it again?
