I just tried this and I quite like it. The filtration is superb, games look great and run smoothly.
Unfortunately, I too suffer from the random white vertical line on the right of the screen and also experience random crashes. Sometimes when I launch a game the emulator freezes, and other times it freezes upon exiting a game, both times requiring a reset.
Everything else works fine though, including button mapping and save states.
Pity, as this emulator displays games the nicest but the minor issues I describe above will stop me using it full time.
SmsGGOO does the job nicely for me. It plays anything I throw at it, whether Master System, Game Gear or SG and it runs games at full speed. It doesn't have the nice filtration but other than that it's a solid and full featured emulator.
