I would like to thanks the anon from the previous thread that told me to try Garegga's Extended Mode. At first I was afraid of trying to go for it, even after finishing countless No Miss runs. Well, today I did my first run and I somehow made it to 2-6 Boss. Man... I can't believe I have the chance to be the first player outside japan to get a Garegga 2-ALL. It can take a whole year, but I'll definitely get it. All thanks to anon's advice.
