I am sorry to say this ggn, but i tried "Golden Axe" in every configuration now and always switched my Falcon off for 10 Seconds before trying the next time, but it refuses to work. No luck for me. :(
Maybe you can have another look at it, if you have the time (only if you have time, you´ve already done so much and you will be surely still very busy!)?

My respects for your hard work, lads! Other Atari Groups can really learn a lot from you, well done everyone! Keep up the good work. Stay cool, stay /|\ ! :)
