What are you playing it on? Such errors are common in joiplay and Linux where the filesystem isn't case insensitive by default. Usually its caused by developer mispelling the filename (e.g. 001-G-water01) or the folder its in (e.g. autotitles), which on Windows is ignored since it doesnt care about the case, but in Linux/Android you have to manually fix it - do "ln -s <name1> <name2>" to create a link with the name that the game wants to the actual file.Game says " Unable to find a file Graphics/Autotitles/001-G_Water01 " when I try and open it.
I've installed both the thing mentioned in OP and RPGVXAceRTP but it still tells me that. Searching the forum gives no solution other than "look under install in OP" but I've already done that.
