There seems to be problem with the music... it doesn't play and if you look in the Gamedetails you'll see that the music entry under media is empty. Did i something wrong while importing it into my existing C64 dreams?
VLC can play SID-Files directly, as Gamebase is point to an unpacked SID-File to play music. About .rsn or .ym i don't know. Maybe a try would help i would appreciate it, as it completes the migration of GameBase somehow
