You can download BlackBerry Desktop USB installation version from
http://www.magmic.com ... Or for wireless download, type
http://bb.magmic.com on your BlackBerry and download the trial version OTA.
Also in the developer forum, some people say they got a Nintendo emulator to "sort of run" on BlackBerry, but didn't work with controls -- some programmer needs to refine the Java Nintendo emulator to work properly (I don't think the 7290 is fast enough though -- need an 8700 or similiar)
The Mario Brothers you saw is for older BlackBerry devices (RIM 950 or 957 models only). It won't work on Java BlackBerries.
