how much did you buy it for? Is it the big or small machine?

Also, unlocking goes by credits, so put it on free play and mash the coin trip in the machine as fast as you can

I bought it for 825 dollars. It is the original arcade machine. How many experience/level points it needs release all characters?

you gonna be there for quite some time hitting the credit button buddy, in the end, its worth it lol

You ever get it to work? Codes worked on my euro version.

I put those up after I got them from a kind soul at Capcom. They work fine. They can be tricky to enter sometimes and I have never figured out why.
