O2Jam U - Guardian Angel - Normal (With SUD+ and One-Hand methods)
These methods are taken from Beatmania IIDX series and I have the SUD+ enabled for the actual Beatmania IIDX game on the arcade with the speed mostly 2.25 or 2.5 depending on the song.
Using the SUD+ method from Beatmania IIDX, I covered about half of the screen but by doing so, it doesn't look like I can use the Jam Combo Boost thingy which is at the top left. Also, having to play one-handed is NOT easy for me.
Serious problem: The experience between Beatmania IIDX and its similar games is NOT going to be exactly the same that I'm not really good at Beatmania IIDX as I'm not used much to the Beatmania IIDX controller which makes that game more difficult to begin with than O2Jam. I surely like both games but I still find Beatmania IIDX as difficult as ever.
