This patch lets the player play freely in the title screen level, rather than having a prerecorded movie play. In case of death, the level will just restart (with two different options: play the death animation and restart, or restart right away. The first option requires AddmusicK or the death song will be wrong). The file select menu will appear once a certain button(s) is pressed (by default, start or select). Check the asm file for the customization options.

(By the way, it's compatible with the retry patch, but there'll be no prompt/instant retry during the title screen).
