Tip: Make sure that ALL exit-enabled pipes, doors, etc. have a screen exit defined, or they'll take you to Level 0, the "endless" bonus game. Unless Start+Select is enabled, the only way out of it is to reset the game.
Tested with: Asar 1.71, SA-1 1.32, LM 3.11 and ZMZ 1.08. Routine tested with PIXI 1.2.15.
Accepted. Please note that this patch won't work with custom sprites that do not rely on the %Star() routine provided (i.e. have the Star routine hardcoded into them). As these cases are contemplated by the readme, that's ok to just accept this. A neat addition to the section, after all.
