So there's this game i'm playing, it's a rhythm game.
When you boot it up, it starts at stage 1 and you can select a song to play.
Then it goes to stage 2 and so on until stage 3 (final) and the credit ends.
Restarting the game every 3 songs is really frustrating.
I know from experience it's possible to loop final stage, so you can always play without ending the credit. Basically when you finish the song instead of going to the game title it goes back again to song select in final stage.
My question is: how can i do it? I tried for hours to find the stage values but they seem impossible to find. Can someone help me?
