I don't know if there is another place for feedback so I'm gonna post it here.
In Reborn mode when it goes from R1-6 to R1-7 there is an error message because it tries to load RE1-7.txt which is instead named RE1-6A.txt in the files. If you press on R1-7 in the chapter select it works fine because that action looks for the RE1-6A.txt file. I've temporarily solved the problem by coping the file and naming one of them RE1-7 and the other RE1-6A so both ways of loading the chapter work. I'm guessing the actual solution would be to have both actions look for the same file name.
Chapter R2-3 has the same problem though this time both ways look for RE2-3.txt. So just changing the name of RE2-2A solves it
