Actually I do not mind those because of all the hard work that went into hacking those game but one that badly need this is Emeral Dragon as the intro is bugged when put on a real pcb and you have to sit through a 45 sec black screen with weird music before being able to skip to the game (which work...

Some guy named Pachichi or something over at Nintendo Age spent money on a mold and sell the shell for 6$ if I remember. Now, since no PCB are available to produce you'll still need to destroy sport games.

Is there an updated circuit for that mod? The thread is so huge and have peoples throwing idea around a lot so I am not sure what is the most up-to-date circuit to use to get the best possible result.
