With this patch, pressing A, B, X or Y while on a level tile in the overworld will activate, respectively, the normal exit or secret exits 1, 2 and 3 and run the corresponding event instantly.
The patch includes a table of which events are allowed to be ran for each level (which is useful for contests/a showoff), but for actual debugging purposes, it's possible to circumvent that table and allow any button press to run any event in any level tile. The table also allows for specified levels to be enterable as normal.
This patch can be very easily removed from your hack.
For the most part, the patch works as it is. The only exception is if you enable !check which makes sense if you take a look at the code: The !check code uses X when it is already used to keep track of the exit type. Fix that and we'll accept it.
