Raiden + basketball - a combination I never saw coming, love it!

Is there a tool you are setting up or docs that will be available for people to make their own custom versions?
No tool, no docs, but you can learn 34010 asm, use notepad++ and compare the code before & after this change.

I'm using actual 90's Midway tools that are 30 years old for all of this, in Dosbox-X.
