Advanced setting andriod?
 

I've been playing Oot Masterquest for the past couple days, get to the point I need to take the frog to lake hylia and it crashed. Great, I do some looking and realize I need more ram but can't find the option that enables advanced settings. Willing to do anything that lets me resume gameplay.

You mean the 8MB expansion pak? Idk how to do that in android, but maybe if you are really desperate you can copy your save to a PC get past that and copy it back.

Is there any way to manually do it in the config?

probably, don't know where tho, shouldn't be hard to find I would think.

Edit: unless the setting is in the RDB, in which case have fun
