So I fixed the issue with the Replay Room.
You'll need to do the following to apply the fix.
1. Decrypt the Game.rgss3a file using the provided RPG Maker Decrypter.exe.
2. Move the decrypted files into the main directory.
3. Delete Game.rgss3a.
4. In the data folder, replace Map057.rvdata2 with the file in the folder labeled "Map File"
During the animation, hold down the SHIFT button to exit it. Some of the longer animations might have you holding the button for a few seconds. The reason you need to hold the SHIFT button is the loop needs to finish where it then checks for the button press and triggers the loop break.
Please note, its pretty buggy and it likes to crash. I've also included a save file that's right outside the replay room.
