Yeah. If you're familliar with ROM hacking, you should know that in Super Mario World when an Exit-Enabled Pipe is placed on a screen with no screen exit, it warps Mario to level 0, which happens to be the End Level Bonus Room assigned to any level occupying a hexidecimal value below 100. (Ex. 0-FF). A copy of it is found on level 100, for any level with a hexidecimal value over 100 (Ex. 100-1FF). Entering via pipe/door and not through the Goal Tape Stars makes it so you never exit. This was "Supposedly" added to prevent someone from cheating and getting 99 lives, but this is not confirmed.
Basically made as a little joke for all you SMW Hackers at SMWCentral.net.
