Mario Bros. coin detection problem

Post by flcl64 » November 30th, 2015, 8:47 pm

Does anyone else experience this?
Mario Bros. has a lot of trouble detecting coins. Holding the button down doesn't help. The game doesn't count the coin until after the button is released, but I'm not sure that's related to the problem.

I have Mario Bros. US, revision F. Is there a different version without this problem?

For anyone else who might be experiencing the same problem, I think I solved it by changing "coin_impulse 0" to "coin_impulse -0.3" in the configuration settings file.

Mario Bros. now appears to register every coin and not at random intervals. :thumbsup:
Hope this'll help some one out there!
