Hi Sparky-D!
I have some great news: I followed your suggestion and created 4GOAL UNITED!
I used everything I've learned so far about loading chains to group all the versions into a single .D64 distribution. I think it’s much better organized now and definitely simpler for people to enjoy all the different modes without any hassle.
Thank you so much for the naming idea and for the encouragement! It really helped me find the best way to wrap up the series.
