Hi,
JPeMu Test - Open back door. Keep the TEST button held in once you've opened the door, and one the machine initialises [the reels have stopped moving and the display says 'CD OPEN / BD OPEN' or something similar, it should make a noise after about 5 seconds and add about 20 credits [just keep the TEST button held down until it adds credits basically!]. Thats Demonstration mode, which is the freeplay one where you can manipulate the reels. To get into Test mode from there, just press TEST again.
JPeMu Speed - if you click Options on the menu at the top, a new window will open. In the middle of that is a box called 'Speed' - you can either check the box called AUTO and the emulator will try to set a realistic speed, or you can change the value in the box. A smalled value will make the machine faster!
Not sure about BFM test mode, if you use Forum Search [in the left hand frame], and do a search for 'BFM test', you'll hopefully find a thread which can help you
