Tip: When determining a time limit, remember that players won't be as familiar with the level as you are. If you normally complete the level with around 100s left on the timer, others might run out of time on their first try.
After collecting 5 or more Yoshi coins, this patch will write "ALL0" (0 = symbol for YC) in place of the 4 coins.
This will also be displayed if you reenter the level.
What the patch writes or does after having collected 5+ Yoshi coins can easily be changed in the .asm file. (See the readme for further information on this)
