Ah ouais en fait il utiliserait bien un bug du jeu...
"If Mario is far on the right side of the screen, the entry point variable will be out of date, so a new entry point will lead to the target of the previous one (Example: In 4-2 of SMB1, if Mario is far enough on the right side of the screen, he can use the pipe to go to the warp room since the destination info of the vine is still valid. Making the vine appear is not required for this glitch. The only thing needed is that the screen hasn't scrolled too far when the pipe is entered.)"
Y a plus qu'à tester
