One of the greatest tools that the 5th Generation of Pokemon games has given the players is the Entralink and subsequent Pass Powers. There are a number of Pass Powers you can obtain, which are split into two groups: those you obtain by developing your Entree by building your Black and White levels, and those that are given by the Entree missions you complete for others, or others complete for you. The personal Entree Powers can be obtained by leveling up your Entree (by doing missions in other copies of Black and White) and selecting them from your Entree once you have obtained the necessary Black or White level to unlock them. The other type of “given” Pass Powers are, well, given to you by other players completing missions for you.
While your personal Entree Powers can be useful, such as the Prize Money and Befriending powers, they only last for 3 minutes or so, and hardly make them economical in terms of the amount of Pass Orbs spent utilizing them. The other type of power, the “given” type, last MUCH longer, up to an hour at the longest, and provide the maximum benefit, without a single Pass Orb spent on your part. However, to obtain such powers depends on two things: another player to give you said power, and random chance that your Entree will give said other player the option to give you the power you want, which makes it hardly reliable.
However, there IS a way to reliably exploit the Entralink, provided you have the resources, so that you can obtain the hour-long Pass Powers you want, as often as you need them.
The first thing you have to know is that you need hardware. You need steady access to at least two Nintendo DS systems, and at least two copies of Black/White. This reason alone is why I am guessing that this exploit hasn’t been widely broadcasted over the internet as of yet. Once you have both DS’ and both copies of the game, you need to have gotten to Nimbasa City in the version you wish to get the renewable hour-long Pass Powers in, and at least have obtained the C-Gear in the other version. As far as I am aware, you also have to have a fully-maxed Entree in the version you wish to use the Entralink Exploit on, so that you may get the Pass Power Maxes (Max is the suffix used to denote a Pass Power lasts one hour). Having a copy of White and one of Black to help speed that process up works wonders.
Now, once you have both copies of the game, you have determined which version you wish to exploit the Pass Powers on, and you have gotten them far enough along that you can enter the Entralink of the version to exploit with, you begin doing the Entree missions. For me, I used Black as the version to exploit with, and White to do the missions on Black. I would use my version of White, connect to my copy of Black, and walk to Black’s Entree and select a mission, complete it, and repeat the process until I had completed five of the six missions. I then saved the game on Black after the completion of the 5th mission. This is VERY important to do. If you’ve been guessing it, you’re right: the top two pips of the Entree Hexagon are the pips to select the “given” Pass Power Max missions, and they are randomly generated pending the completion of a “mission cycle”. The reason you save the game after the completion of the 5th mission is to enable yourself to soft-reset the soon-to-be-exploiter version.
Now then, once I saved Black after the successful completion of the 5th mission, I went back in with White, walked to the Black Entree, completed the final mission, and was put back in White’s Entralink, just like always. I then re-entered Black’s Entralink with White, checked the Black Entree, and found that the new “mission cycle” was up, and that the top two powers were “Exp Point Power Max” and “Befriending Power Max”, which were both different from the last mission cycle, and not unexpected. Well, those were the two powers I did not want, so I soft-resetted Black, re-did the 6th mission on it, and re-entered the Black Entralink with White to once again examine the Black Entree. This time, the two Pass Power Maxes were Befriending Max and Prize Money Max, again, not what I needed. So, I soft-resetted again and the cycle continued.
I kept this up until I obtained the Holy Grail of Pass Power Maxes on Black, Hatching Power Max and Exp Point Power Max. These Powers allowed me to give my Black version the power of increased egg hatching rates and increased experience point gains from battle for one hour each, an absolute blessing for the Pokemon Breeder in us all. Afterwards, I saved the Black game and restarted it, and re-checked with White to see what I suspected: I had kept those options for missions to complete in Black. Therefore, by using the White game as the initiator and redoing the missions to give Hatching and Exp Point Max, I could give my copy of Black an infinite amount of Hatching Power Max and Exp Point Power Max, at any time I so desired, VASTLY reducing the amount of time and Pass Orbs spent hatching eggs and raising newly-trained Pokemon.
Keep in mind, though, that the method to getting these ideal Pass Powers was by random chance; it took me six straight hours of play to get the two “perfect” powers. You also have to remember that to utilize them to the fullest, a second DS and a second copy of the game is necessary in order to both give yourself the power and to give it to yourself on a basis that is convenient to you. While it is a time-consuming process, the amount of time you save in hatching eggs and leveling your Pokemon MORE than makes up for it, and greatly reduces the stress of breeding.
Some last notes that should be mentioned: as you know, there is a time limit on the missions, despite the fact that they are re-takeable. If you fail a mission to give yourself a Pass Power, the mission WILL change, and you will be randomly given another Pass Power mission. If that is the case, DO NOT PANIC. You can simply soft-reset and the game will treat the change as if it never happened. Also, once you have your ideal Pass Powers, do NOT allow others to complete your mission cycle on your cart. Even though you can perpetually give yourself those Pass Power missions, if you complete the hexagon set, all the missions will again randomly generate. Just be careful, and if you have the time, money and resources, you can give yourself the greatest breeding tool of all time.
