Zanzara

hey, i wonder if there is a way getting any of the metal slug 5 sets to work? i mean i absolutely can nowhere find 268-m1_decrypted.bin with 524k. all i find do have 65k size. the closest i got is a 268-m1d.bin with the right size of 524k. so i tried to rename it to decrypted. well the game did start but the graphics were totally messed up.
