This is a combination of the three standard autoloaders I've developed, all you need to do to switch between them flip the on/off toggle to on next to the type of cannon you are using (battle, artillery or bertha cannon) and then connect the on/off inputs/outputs to all the right places. Pretty easy to set up and use since everything is labelled properly.
Disclaimer: I do not need credit if you use this microcontroller, there are plenty of them around already, this is just the one I made.
