Under the tab menu, I maxed out the mouse sensitivity. It takes a little bit of the "madness" out of spinning the trackball while playing.
Also there is a dip switch setting for difficulty in the Tab menu for MM. However, I found mine was already set in easy.
Someone said they prefer the NES versions of games.... I find arcade titles were designed to bring in revenue and are all overly difficult. The console titles are far more entertaining. Conversely, puzzle games benefit from the added pressure in arcade format.
