I see the disks are listed seperated. Not a good idea.
Use one row for each game.
You tried winuaseloader? As I copied you my bat file. Winuaeloader must first be configurated. I can send you my standard .uae wich works good for many games. Left-mouse = 1, Rigfht = 2, F1 = 1, Game start = 5 ...and of course ESC to go back to EL.
